Johnson said this it is not recommended for airplanes to be so close to each other.
"Visibility was not a factor. Weather was not a factor. They saw each other," Johnson told ABC. "The fact of the matter is they were both willing participants in this maneuver that, unfortunately, had disastrous results."
As Sprague was flying, Veal pulled up on the left side of her plane, at which point the two were "neck in neck, going the same speed," Johnson said. Then, Veal went up and over Sprague's plane to her right.
Sprague recalls saying, "Scott, I can't see you" and Veal saying to her, "Whatever you do, don't pull up."
The next thing Sprague knew, her boyfriend's plane had clipped her right wing.
Veal's airplane passed underneath her from the right to the left and nose-dived into the ground.
Veal was killed when the plane burst into flames. The aircraft was almost entirely destroyed upon impact.
With minimal control over her damaged plane, Sprague was able to safely land. It took four hours for rescue helicopters to be able to pick her up.
