Not a very good airline !
Looking around Brize Norton I could be mistaken that it was part of Duxford's old airliner collection, Having worked some of the transport assets when I was an engineer for BA I can tell you that the aircraft were getting on a bit 20 years ago.
I have the upmost respect for the people who maintain and fly these very old aircraft and keep them flying but dispite the efforts of these people the serviceabilty rate would bankrupt an airline within weeks.
The bottom line is that these aircraft should be replaced now but I suspect that on the goverment list of what to spend my taxes on the transport fleet is well south of a number of trendy social programs.
