Re: A beautiful aircraft though - Possibly the loudest thing I've ever seen move.
Yeah - I've witnessed a Vulcan both quiet and loud. Last year it flew over the old runway at Filton (Bristol) - it was quiet and graceful. Must have been around 1980 at a British Aerospace open day at the same location I witnessed a near vertical climb from quite low above the ground. That was loud ... very very loud! To this day the loudest noise I have ever heard ... and felt through my body! I don't think they perform climbs quite like that with X558 because of the age of the airframe.
