XH558 had a problem extending the front u/c, when landing at Prestwick after the Scottish show.
Vulcan bomber makes emergency landing at Scottish Airshow after landing wheels become stuck during fly-past - Mirror Online. Less dramatically, there's a very interesting youtube clip where someone has recorded the comms and video as a BBMF Spitfire flies in formation to have a look for damage/obstructions. All very professional, the Vulcan crew blow the gear down and land. I noticed that the gear did not appear to fully extend when cycled during the display. I hope they get her fixed for the remaining appearances before she's consigned to the ground.
