Hey
The Maxjet 767's are indeed second hand. N250MY is a Previous Qantas aircraft, and even a domestic flight in Aus is a fair distance, so i assume she has clocked up some miles in their time in the skies. And N260MY has been with TWA, Aero Continente, TACA, Braathens, Britannia and Varig, so she has had her fair shair of miles aswell. They are reliable, but i must admit, they do go tech quite often, but i think alot of it is that they pride themselves in being safe, so even the slightest problem and they will go "tech". it has been known for Max pax to be flown out on EOS if their is room. But judging by MAX being very popular lately, i dont think you could fit the passengers on EOS, so i assume they would just wait for the flight too leave, or be flown out on the next available.
I believe the MAXjet flight that has gone tech today is leaving STN tonight around 2230 time.
