411
Sorry but I am not fully up to date on Name changes of L1011 operators, some of which I cannot pronounce.
Usually only the name has been changed to protect the guilty
I usually know the aircraft but cannot always put a face to it
I guess there are a couple of reasons why you dont admit to the airline.
One is that you want to keep it secret and the other is that it may have changed during your posting
Anyway give my regards to Abu Sheik.
