Understand at LTN though that either the Easy Hangar would have to be shortened or the buildings adjacent to the taxiway link,( currently being worked on again) demolished to allow the wingspan needed to get the 787 to the main Apron and manouverability into any Hangar there.
Many years ago the first 747 that came to Luton parked on the main apron. Does a 787 have a bigger wing span?
