Are you guys serious about 757 or DC-8s using BGBW or do you mean Sondestrom? BGBW is Cat A and B only. BGBW only has 6004 feet of total runway length
Yes, I watched an SK DC-8-63 land at BGBW on more than one occasion back in the eighties - I would not have believed it if I hadn't seen it. Charters from Copenhagen, I think.
On that occasion I was passing through on ferry flights quite frequently.
