Let's just stay with the facts shall we.
Wingtip loss number 1: Right hand wing versus tail dock, Melbourne Jet Base. LAME
Wingtip loss number 2: Left hand wing versus stationary B737 elevator, Brisbane Hangar. LAME.
Wingtip loss number 3: Left hand wing versus stationary AirNZ B737, taxiing from Christchurch Hangar, Flight Crew
Wingtip loss number 4: Left hand wing versus Jetstar APU Exhaust, pushback Melbourne Airport. Ground Crew.
It's pie in the sky stuff to say that if it was a LAME it wouldn't have happened.
