Just before a midair collision that killed six at a Dallas air show, a group of historic fighter planes was told to fly ahead of a formation of bombers without any prior plan for coordinating altitude, according to a federal report released Wednesday. The report did not give a cause of the crash, the AP reports. A P-63 Kingcobra fighter was banking left when it struck a B-17 Flying Fortress bomber behind the left wing during the Nov. 12 air show featuring World War II-era planes, the National Transportation Safety Board said in its preliminary findings. All six people aboard the planes—the pilot of the fighter and the bomber's pilot, co-pilot and three crew members—died as both aircraft broke apart in flight, with the bomber catching fire and then exploding on impact.
There had been no coordination of altitudes in briefings before the flight or while the planes were in the air, the NTSB said. The report said that the Kingcobra was the third in a formation of three fighters and the B-17 was the lead of a five-ship bomber formation. Eric Weiss, an NTSB spokesperson, said the agency is trying to determine the sequence of maneuvers that led to the crash. It is also examining whether such air shows normally have altitude deconfliction plans. “Those are precisely the types of questions our investigators are asking,” Weiss said. “What was the process? What’s the correct process? And what happened?”
John Cox, a former airline captain with more than 50 years’ experience, was surprised that the NTSB found there wasn’t an altitude deconfliction brief before or during the flight. He said these take place in other air shows, but he’s not certain whether they’re standard for the Commemorative Air Force, which put on the Wings over Dallas show. A person familiar with the show’s operations that day said the air crews were given general altitude direction in their morning pre-show briefing. However, there was not a discussion of specific altitudes for each pass the aircraft were going to perform, said the person, who was not authorized to discuss the matter publicly and did so on condition of anonymity.
