Extraordinary in my mind is when there is a failure following proper manufacturer approved inspection and preventative maintenance programme. Airlines don't run their aircraft like many car owners, skimping on maintenance and waiting until they break down. And let's face it, how often do they actually break down? In 20 years I think I can count only remember a dozen or so of flights that were cancelled due to technical failures. Most of our cancellations are due to weather, ATC, airport disruption, crew problems and passengers.
And can anybody tell me why airlines have been picked on by the EU? Ships, trains, busses appear to be exempt. Also maybe it's about time ATC was fined for their involvement? Let's just have a level playing field.
