July 27, North Las Vegas, Nev. / Lancair IV-P

At about 1045 Pacific time, an amateur-built Lancair IV-P was damaged during takeoff from North Las Vegas Airport. The pilot suffered minor injuries and two passengers were not injured. The pilot said the airplane settled back on the runway after rotation. He continued the takeoff and the airplane again became airborne, then drifted to the right side of the runway and settled again, causing the landing gear to collapse. The pilot said he had been advised by air traffic control prior to departure of possible wake turbulence. He thought he had waited about one minute before starting the takeoff.
