Gulf Air 151
Apparently GF 151 had a runway change in BKK from 21R to 21L on April 6th and "Raouffed" the take off run. Apparently it took out a tree at the end of the runway and the loud bump was reported to cabin crew by pax. However the A340 continued to BAH with vibrations coming from No 2 engine (which has ingested part of the tree, the rest being stuffed into the u/c bay on retraction.
On gear extension into BAH a hydraulic system was lost and to cap it all a precautionary evacuation was carried out.
A big hush up?
