This appeal arises out of the defendant’s conviction under three counts of an indictment charging him under § 2, 18 U.S.C. with aiding and abetting in violations of Sections (a), (b) and (d), of the federal bank robbery statute, § 2113, 18 U.S.C. The defendant has appealed only from his conviction under count three of the indictment relating to the charge under §§ 2113(d) and 2. He raises as his single ground of appeal the district court’s alleged failure properly to instruct the jury.
At trial the defendant’s counsel submitted a request for certain instructions among which was one that, in a prosecution for aiding and abetting a bank robbery under §§ 2113(d) and 2, the jury should be instructed that “the government must prove not only that the Defendant knew that a bank was to be robbed and [that the defendant] became associated with and participated in that crime, but also that the Defendant knew that the criminals were armed and intended to use their weapons, and that he intended to aid them in that respect.” He cited United States v. Short, 493 F.2d 1170 (9th Cir. 1974), as authority for the quoted requested instruction. The district judge stated that the requested instructions, including those not in dispute here, would be given in substance by him in his instructions to the jury.1 After the *997completion of the testimony and arguments of counsel, the district judge instructed the jury.
In his instructions the district court set forth the elements of an offense under § 2113(d). He very specifically instructed the jury that the charge required proof that the robbers had “enter[ed] a bank carrying a weapon or something which appear[ed] to be a weapon saying that if you don’t give me your money, I’ll inflict serious harm upon you or making any reference at all to the use of force .. . . ” The district judge then instructed the jury that, if you find that the robbers in the course of this robbery had “assaulted [the] bank employees by putting their lives in jeopardy by the use of or the threatened use of deadly weapons,” it should proceed to determine “whether or not the defendant aided and abetted [the actual robbers] in the commission of such acts.” He thereupon stated the circumstances under which it could be said the defendant had aided and abetted the robbers under § 2, 18 U.S.C.; “The Court instructs you that in order to aid and abet another to commit a crime it is necessary that the accused, that is, the defendant in this case, willfully associated himself in some way with the criminal venture, that is, the bank robbery, and willfully participated in it as he would in something he wishes to bring about, that is to say that he willfully seeks by some act or omission of his own to make the criminal venture succeed and that an act is willfully done if done voluntarily and intentionally and with specific intent to do something the law forbids ....” 2
At the conclusion of the charge, in which was included an extremely fair statement of the defendant’s own contentions, the district judge addressed counsel for the defendant, inquiring whether there were “[a]ny requests for additional instructions to the jury from the defendant?” The defendant’s counsel replied, “No, sir.” The district judge went on to inquire whether the defendant had “[a]ny objections to the instructions?” Again, counsel for the defendant responded, “No, sir.” However, the defendant now contends in this appeal that the district judge should have instructed the jury as requested in his proposed instruction that the Government had to prove that the defendant knew that his co-defendants (the actual robbers) “were armed and that they” intended to use their weapons, and that he intended to aid them in that respect. Since he did not raise this objection properly at the conclusion of the district judge’s charge, the defendant concedes that such failure to charge will support reversal only if that failure is held to be clear error.3 The defendant, however, claims that this failure to instruct was clear error citing United States v. Short, supra, and United States v. Sanborn, 563 F.2d 488 (1st Cir. 1977) as authority for such contention. This claim of error is the sole issue on appeal.
*998We may assume for purposes of this appeal that under both Short and Sanborn, one charged as an aider and abettor under § 2113(d) should be entitled, if the point be timely raised, and if the essential facts be in dispute, to an instruction that the defendant knew that his co-defendants who perpetrated the actual robbery were armed, thereby putting the defendant on notice of the likelihood that in the common criminal enterprise a gun or other dangerous weapon would be used. While it may appear somewhat unreasonable to assume that any one would undertake to rob a bank without a gun or other intimidating weapon, it is the rule as stated in Short and Sanborn that one charged as an aider and abettor under § 2113(d) should be shown to have known that his confederates in crime were armed and thus likely to jeopardize lives in the course of the robbery by the use of their weapons.4 But all this reasoning rests upon the assumption that there is a genuine dispute in the record whether the one charged with being an aider and abettor had knowledge that his co-defendants, the robbers, were armed when they, embarked upon their act of “sticking up” the bank. That this is the necessary predicate upon which the rule in these two cases rests is manifest in the analysis used by the court in both cases and in the statement by the court of the actual question decided in those cases.
In Short the court charged the jury that a defendant, indicted as an aider and abettor in an armed bank robbery, need only know “that a bank robbery was going to be attempted or accomplished” by his co-defendant to be guilty and this is so “whether or not he knew that [the actual robber] was armed or what he was armed with” since this latter fact “is not necessary, not a necessary element to the crime.” 493 F.2d at 1172. It was that instruction which the defendant, under the facts of that case claimed to be, and the court found, erroneous. In Sanborn, the court, at two points in its opinion, made clear that this was the specific question it was addressing: First, the court said explicitly that the question before it was “whether the court erred in declining Sanborn’s requested instruction that his knowledge of the gun had to be proven.” Later in the same paragraph, the court again identified the specific question it was answering by its decision:
“Still, if the accomplice’s knowledge of the weapon forms part of the Government’s burden of proof in establishing the aiding and abetting of an armed robbery, it would be error for the trial court not to so advise the jury upon request. We must, therefore, decide that question.” (Italics added) 563 F.2d at 490.
In answering the question as phrased by the court in these two statements, the court in Sanborn said that the Government must show that the defendant “was on notice of the likelihood that a gun or other dangerous weapon would be used in the robbery.” But it suggests that such “notice of the likelihood” of the use of the gun may be inferred from knowledge of the possession of the gun by the confederate robber. And it adds that had there been an instruction along this line, it “would have no hesitancy whatever in affirming the present conviction” but, “[a]bsent any such instruction following upon defendant’s explicit request,” it felt obliged to reverse. 563 F.2d 491.
As this review of the facts in those cases shows, the ruling in both Short and Sanborn arose only because the evidence was in dispute in those cases as to whether the one charged as an aider and abettor was aware that his robber confederate was armed and thus likely to use his weapon in connection with the robbery. If the evidence is not in dispute on the knowledge of the aider and abettor, the question resolved in those cases does not arise.5
*999Contrary to the facts in Short and San-born, however, there is no dispute in this case that the defendant did know that his confederates who perpetrated the robbery were armed. For several days before the bank robbery, the defendant had been riding around with his co-defendants Jackson and Tijuan McCaskill in Jackson’s Cadillac Eldorado. In the course of these rides, these co-defendants — Jackson, in particular —discussed, in the presence and hearing of the defendant, their prior ventures in crime, including bank robbery. The defendant so testified. Thus, Jackson and Tijuan McCaskill were known to the defendant to be persons with criminal experience. The talk among the three related at times to a criminal venture in which the three would engage and in which the three would share equally. That venture discussed among the three was one “to stick up a bank.” Such a venture certainly would contemplate the use of some weapon with which “to stick up” the bank. And the defendant’s co-defendants had such weapons. Both were armed, one with a 38 Smith & Wesson gun and the other with a 6 millimeter automatic.6 The defendant knew his co-defendants had these guns or, as he said, were “carrying the guns.” He so admitted to the FBI investigator and has never contradicted this admission. Not only did the defendant know of the plan “to stick up a bank” and of the ability of his co-defendants, with their guns, to do this but, in addition, he knew, by his own admission, the bank which was to be “stuck up.” He admitted that the Bessemer City bank had been identified in the conversation of the three as a “sweet lick,” which the defendant said he understood to mean that such bank “looked like a good place to rob.” Moreover, the parties agreed among themselves, including the defendant, that the monies gotten in the proposed robbery of this “sweet lick” should be divided three-ways, with the defendant receiving one-third.
Having made this plan “to stick up a bank,” the three got together in Jackson’s Cadillac Eldorado on the morning of the robbery. After riding around for a while, they “proceeded to Bessemer City, circled the bank [which represented the ‘sweet lick’], checked it out,” and then parked their car a short distance away from the bank. The defendant was told to wait in the car for them, providing the robbers with a getaway car after sticking up the bank. The defendant’s co-defendants proceeded to the bank. In his confession given the FBI, which the defendant never repudiated or impeached, he said that “he knew that both Jackson and Tijuan McCaskill [his co-defendants] were carrying pistols when they went into the bank.” On cross-examination, the investigator — again without contradiction from the defendant — repeated this account of the defendant’s confession, adding: “He [referring to the defendant] said he didn’t see the guns when they went in the bank. He knew they had them and had been carrying them for several days.” It is difficult to envision clearer proof of knowledge on the part of the defendant that the criminal venture in which he and his two co-defendants were engaged was “to stick up a bank” and that his co-defendants who were to do the actual “sticking up” had the guns with which to effect this object. The evidence of a planned armed robbery of a bank, in which the role of the defendant was to be that of the driver of the getaway car as he himself confessed, is thus overwhelming.
*1000After the co-defendants had “stuck up the bank,” they seized a car adjacent to the bank, drove it hastily the short distance to the point where the defendant was awaiting them. They jumped into the car. The defendant, who was seated in the driver’s seat with the ignition on, drove off. As he was proceeding out of town, a fast moving police car driven by officer Huffstetler, responding to a report of the bank robbery from the Bessemer City police department, passed him going in the direction of the bank. As the driver of the police car passed the defendant, he observed that the car and the occupants seemed to match the description given by those about the bank at the time of the robbery and passed on to him by the Bessemer City police department.7 The officer turned his car around and began to pursue the car driven by the- defendant. The defendant saw the police car in pursuit. He sought, by accelerating dangerously his speed and maneuvering among the streets, to evade the pursuing officer while his co-defendant McCaskill began shooting at the pursuit car. The defendant, identified by officer Huffstetler, as the driver of the Eldorado, was driving at a speed in excess of ninety miles an hour but,8 as he sought to maneuver at that speed in a shift from one road to another, he lost control, sped off the road and turned over.9 His co-defendants began shooting at the pursuing officer but, when reinforcements arrived, all three of the defendants surrendered. It was after their arrest that the defendant gave his confession.
The defendant did seek to excuse his part of the robbery by declaring that “he did not go into the bank himself and did not take part in that part of the robbery” but he admitted he was the “driver of the getaway car.” The defendant seemed to assume that if he had not been in the bank at the time of the actual armed robbery, even though he had known of the plan to “stick up” the bank, and knew that his co-defendants were armed “when they went into the bank,” he could not be convicted, despite the fact that he waited in the driver’s seat in the car until the two robbers returned and then immediately drove them off in the planted getaway car. However, as the court said in United States v. Von Roeder, 435 F.2d 1004, 1010 (10th Cir. 1971), cert. denied, 403 U.S. 934, 91 S.Ct. 2264, 29 L.Ed.2d 713:
“The escape phase of a crime is not, . . . an event occurring ‘after the robbery.’ It is part of the robbery. One who participates in and assists in the escape of the parties who were in the bank aids and abets the bank robbery . ...” 10
Nor is it important that the defendant himself was unarmed or that his role was only that of the driver of the getaway car; he still was properly convicted of arm*1001ed robbery when he admitted “he knew [that] others he identified as robbers [with whom he was associated in the criminal enterprise] were armed with guns.” This was clearly declared in United States v. Johnson, 390 F.Supp. 1049 (E.D.N.Y.1975), aff’d., 525 F.2d 999, cert. denied, 424 U.S. 920, 96 S.Ct. 1127, 47 L.Ed.2d 327 (1976), where the defendant had acted merely as a guard while others actually committed the armed robbery. In finding him. guilty of armed robbery the court said (390 F.Supp. at 1056, n.5):
“Although the defendant’s confession shows that he was unarmed, his other statements make it clear that he knew others he identified as robbers were armed with handguns. Defendant is therefore guilty as a principal as charged in Count Two [i.e., the charge under 2113(d)].” 11
Accordingly, even if Short and San-born are correct that a district court should instruct the jury that, as a basis for conviction as an aider and abettor in an armed bank robbery, the defendant must be shown to have known that his confederates were armed at the time of the robbery and that, the omission of such an instruction, when properly demanded, warrants reversal, such authorities are inapplicable here, where there is no question that the defendant had such knowledge. That is exactly what was held in United States v. Johnson, supra, 390 F.Supp. at 1056, n.5. In that case, the defendant’s knowledge that his co-defendants “were armed with handguns” was sufficient to establish his guilt as a “principal” in the armed robbery. That is the critical distinction between Johnson and this case, on the one hand, and Sanborn and Short, on the other: Here the defendant knew his co-defendants were armed “when they entered the bank.” That knowledge, undisputed by the defendant, made him responsible as a principal in the armed robbery. The crime of armed robbery, so far as the defendant was concerned, was complete. There was under those circumstances no need, as there may have been in Sanborn to instruct the jury, “that his (i.e., the defendant’s) knowledge of the gun had to be proven.” 563 F.2d 490. That was a fact the defendant admitted and was overwhelmingly established.
There is another and an even more compelling reason why neither Short nor Sanborn is applicable here. In both of those cases, the failure to instruct that the government should prove the defendant’s awareness of the possession of a gun by his confederates in order to establish an aiding and abetting charge was timelyobjected to; in this case, it is admitted that the defendant did not make a proper and timely objection. Even if the district court erred in failing to include an instruction in this case that the jury must find that the defendant had knowledge that his confederates were armed when they entered the bank, it is settled law that a defendant is precluded from relying on such error because of his own failure to object to the omission in the manner prescribed by Rule 30 of the Federal Rules of Criminal Procedure, unless it can be fairly said that the district judge’s failure under the. facts of that case so to instruct was plain error within the meaning of Rule 52(b), Fed.R.Crim.P., United States v. Whiting, 311 F.2d 191, 197-98 (4th Cir. 1962).12 Rule 52(b), Fed.R.Crim.P., which permits an appellate court to notice “[p]lain errors or defects affecting substantial rights ... although they were not brought to the attention of the court,” however, “was never intended .. . [to] be applied in such a way as to destroy Rule 30, which provides that no party may assign as error any portion of the charge to the jury unless he objects thereto before the jury retires stating distinctly the matter to which he objects and the grounds, of his objection.” *1002United States v. Ostendorff, 371 F.2d 729, 731 (4th Cir. 1967), cert. denied, 386 U.S. 982, 87 S.Ct. 1286, 18 L.Ed.2d 229; United States v. Bryant, supra, 612 F.2d 803; United States v. Graydon, 429 F.2d 120, 123-24 (4th Cir. 1970); United States v. Jones, 340 F.2d 599, 600 (4th Cir. 1965), cert. dismissed, 381 U.S. 907, 85 S.Ct. 1456, 14 L.Ed.2d 430; United States v. Lawrenson, 298 F.2d 880, 884 (4th Cir. 1962), cert. denied, 370 U.S. 947, 82 S.Ct. 1594, 8 L.Ed.2d 812; United States v. Gerald, 624 F.2d 1291, 1300 (5th Cir. 1980), cert. denied, 450 U.S. 920, 101 S.Ct. 1369, 67 L.Ed.2d 348; United States v. Simmons, 281 F.2d 354, 356 (2d Cir. 1960). Accordingly, the plain error rule, 52(b), as an exception to the requirement mandated under Rule 30, is always to be applied cautiously and only in the exceptional case where, after reviewing the entire record, it can be said the claimed error is a “fundamental error, something so basic, so prejudicial, so lacking in its elements that justice cannot have been done,” 13 or “where [the error] is grave error which amounts to a denial of a fundamental right of the accused,” 14 or the error has “ ‘resulted in a miscarriage of justice or in the denial to appellant of a fair trial’ ”15 or where the error is such as to “seriously affect the fairness, integrity or public reputation of judicial proceedings”16 or where it can be fairly said “the instructional mistake had a probable impact on the jury’s finding that the defendant was guilty.” 17
As the Supreme Court said in Henderson v. Kibbe, 431 U.S. 145, 154, 97 S.Ct. 1730, 1736, 52 L.Ed.2d 203 (1977), “[i]t is the rare case in which an improper instruction will justify reversal of a criminal conviction when no objection has been made in the trial court,”18 on the basis of the “plain error” exception in Rule 52(b). See also to the same effect, United States v. Tom, 640 F.2d 1037, 1041 (9th Cir. 1981); United States v. Palmeri, 630 F.2d 192, 201 (3d Cir.), cert. denied, 450 U.S. 967, 101 S.Ct. 1484, 67 L.Ed.2d 616 (1981).
Neither can it be said that the failure so to instruct would be clear error where the defendant’s awareness that his confederates were armed is admitted. When one’s confederates enter a bank armed for the purpose of robbing the bank, the likelihood that the confederates may use their weapons is manifest. There could be no miscarriage of justice arising out of a failure by the district judge to instruct that the jury, in order to convict the defendant in this case, would have to find that the defendant knew his confederates were armed when they entered the bank. The defendant knew his confederates were armed, as he said, when they entered the bank. He had ridden with his confederates on a number of occasions in the days immediately preceding the robbery. He admitted that he knew the confederates were carrying guns on those occasions. There can be no “fundamental error,” no “miscarriage of justice,” nothing “seriously affect[ing] the fairness, integrity or public reputation of judicial proceedings” in the failure of the district judge in such a case as this to instruct the jury that it must find that the defendant knew his confederates were armed.
We would add that we are by no means certain that the reason the defendant’s counsel did not except to the instructions *1003given by the district court was that he recognized that those instructions did cover all the elements of the crime of aiding and abetting the commission of an armed robbery under the facts of this case. The instructions may not have been as explicit as he would have liked but the instructions were clearly adequate and warranted no exception. In any event, when it is shown beyond dispute that the actual armed bank robbers, to the knowledge of a defendant, were armed and that the defendant had aided them, whether as a guard, as in Johnson, or as a driver of the getaway car as in this case, there is no miscarriage of justice in a jury finding that he is guilty as a principal of the crime of armed robbery under § 2113(d).
Accordingly, the judgment of conviction is
AFFIRMED.
