Reasonable compensation ???
Without sounding sarcastic but since there is no other way, the fact that you are still a living, breathing human being, and we are not reading about you in the newspaper because the airplane went mechanical inflight is compensation enough for me and should be for you.
Aircraft are mechanical devices, designed by human beings, built by same, operated by same and fixed by same..........as they say "excrement occurs"....so, just be happy it was on the ground.
Don't take it personally as I don't know you....but when anybody complains about delays due to mechanical breakdowns, it really annoys me, because they don't seem to understand what the alternative could have been..............
