As a hired consultant to several agencies looking into the crash, O’Roark analyzed radar data from a number of reporting stations. When contacted by Stalcup to appear in the documentary, O’Roark agreed. They met at a hotel near Dulles Airport.
“He wanted to know about the radar,” O’Roark told me. That was fine with O’Roark. He knew the blips Stalcup was referring to. “He’s got one little hit that first appears simultaneously with the fragmentation,” about a mile and a half off the right side of the airplane.
O’Roark said he told Stalcup, it could be the airplane, it could be a boat or a ship, it could be a false high-speed target. Since a primary radar return doesn’t give altitude, there’s no way of knowing where in space the object actually is, or as O’Roark said, “Things that appear to be close together could be quite far apart.”
O'Roark quibbled with making any conclusion about the speed either. "Specifically I said, you can't tell velocity by the primary return until you get a second return." But by the time the radar swept by four and a half seconds later, there were 700 primary returns. Whatever happened to the plane had already happened.
Curiously, not a frame of this interview appears in the film. Perhaps because O’Roark also told Stalcup he thought the missile theory was nonsense. When I pushed O’Roark to think long and hard, asking “Is there any possible way, even if it is extremely remote, that the radar images you guys talked about could be interpreted to be a high-velocity explosion next to the airplane?” O’Roark said, “Call me in 3 hours, maybe then I’ll be drunk enough to think so.”
