Narrative:

No narrative. Callback conversation with reporter revealed the following information: the reporter was on his way to an air show and was staying between the 2 alert areas using a highway as his guide. He simply went into a wing over maneuver and hadn't cleared the area behind him. The 2 T37's were originally sighted ahead of him as he was flying wbound. They later turned around and were behind him when he did his aerobatic maneuver. He just did not know that they were there. The wingman moved off from the lead aircraft as a result of his proximity.
