Me? I would strap on an A380 any day, GP7200 powered of course. With a RR900 engine, I would prefer they first have a definitive answer to why this occurred before flying it again. Whatever it was, it was outside what was anticipated or foreseen. Not a happy situation for A380/RR operators to be in.
Of course they all agree with you, thats why they have been working so hard for the last couple of days to address the issues to put the fleet back in the air.
One can't expect the general public to know whats going on behind the scene but you can expect that when a major airline puts their fleet back in the air that they are darn sure that they are satisfied.
