A total of five Qantas airline flights were delayed or canceled between January and March 2006 because of “wasp infestation.” Yes, apparently, wasps had built 20-30 nests inside parts of the A330 planes while they were waiting on the runway, according to BBC.
While the plane was taxiing away from the runway, the pilots noticed the brake temperature rose to 685C, causing six of the eight main landing gear tires to deflate. Smoke was coming from the main landing gear area, but nobody was hurt (aside from the wasps).
Qantas and the airport operators have been criticized for responding too slowly to the wasp infestation but a subsequent “enhanced pest eradication program” had now brought the problem under control. Man wins again!
