MARTINSBURG, W.Va. (AP) — Investigators say the pilot of a plane that crashed during an air show in West Virginia was doing a climb and rollover maneuver with another aircraft before his deadly descent.

Spokesman Peter Knudson of the National Transportation Safety Board said Sunday John "Jack" Magnan was about 300 feet above the runway when he began his climb at approximately 275 mph.

Knudson says Magnan's T-28 Warbird did not complete its roll before it began its descent.

He says there was no indication of trouble before Magnan's aircraft plunged to the ground.

Knudson says the investigation is likely to be difficult because of the damage to the plane from the fiery crash.
