The front canopy of a civilian-operated Aerovodochody L39 Albatros single-engine jet separated from its moorings on takeoff from Wittman Regional Airport in Oshkosh, Wisconsin, on departure from EAA AirVenture. The pilot and sole occupant of the two-seat jet was apparently uninjured and is shown on the accompanying video making a safe landing after returning to the airport.
The video was captured by occupants of an aircraft waiting in line for departure from the show and posted on YouTube yesterday (July 31). According to reports, the canopy landed on the runway and was sufficiently undamaged that the aircraft was able to leave later the same day.
An internet search also turned up this video of a similar situation posted nine years ago.
