After the controller warned the helicopter about the plane taking off, the Marine One pilot said he saw the traffic and declared, “We’ll be doing a momentary delay.”
Guzzetti, who is a former crash investigator for both the NTSB and FAA, said he doesn’t fault the controllers because they never heard Marine One’s warnings. And once they did realize the helicopter was taking off, they quickly warned the pilots and ordered another plane coming in to Reagan to abort landing and circle around.
“In this case, the controller did absolutely nothing wrong. He did not receive the transmission saying that they were three minutes away from taking off. So he had no reason to hold the airplane that was lining up and waiting,” Guzzetti said.
After last year’s midair collision, it became clear that poor communication between air traffic controllers and the military had been a longstanding issue. During a congressional hearing, it came out that a hotline connecting the Pentagon to the tower at Reagan hadn’t been working for more than three years, and the FAA hadn’t even realized it.
The NTSB said that after this incident involving Marine One, FAA technicians determined that there wasn’t adequate line of sight between the radio receiver at the airport and the location where the helicopter takes off at the White House. So those radios were moved from the neighborhood where they had been located to the top of the tower at Reagan. Subsequent tests showed the radios working well after that change.
