ETOPs - Many airlines are starting to use ETOPs philosophy on 3, 4 engined aircraft. ie: a technician cannot service all engines eg: oil replenishment, change MCDs, fuel filters etc. etc. As for regulations, FAR, EASA and others on ETOPs diversion - I'll leave that to those who are up to speed on it.
The A380 just doesn't look right, large wing span, short fuselage (though I suppose it gives room for extending it using the same wings) There is a saying "If it looks right, it s right".
Why is it that a thread starts out with good intent that it usually ends in a mud slinging match - value others' opinions even if vastly different from your own.
As for preference for Airbus or Boeing - surely the airline bean counters work out which aircraft gives good value for money in Ops, maintenance and financial deals before deciding which one to buy? (Not because it is American or European) and hopefully not because governments apply pressure to buy home grown products!!
Phew glad that is off my chest
