På a.net forumet kan man lese følgende:
"It didn't fall off while inflight, there was a ground accident at
CPH some days ago and the mechanics removed the winglet which caused a six hour delay for the departure to
IAD."
Vist en går utfra at dette stemmer og siden det tydeligvis ikke er high-speed tape over WL festet, kan selve tapen ha blåst bort innflight?
