 However, the NTSB determined that V1 was not relevant to this incident because it is only intended to advise pilots on whether they can abort after engine failure, and the first officer believed that his aircraft had been physically damaged and might not be capable of flight.As a result, the NTSB found the first officer's decision to abort was reasonable, but criticized the pilots for failing to execute the abort rapidly.One NTSB board member, Francis H. McAdams, wrote in a separate minority report that he would have concluded that an abort was both reasonable and necessary under the circumstances, despite the fact that the aircraft had exceeded V1 and was certain to overrun the runway.
