It's nice we don't get too quickly dinged by the mods for off-topic, 'cause my tail would be fried by this one. http://www.bbc.co.uk/dna/hub/A698231 is a list of airline call signs. I'm not sure it's too authoritative - e.g they list speedbird for BA, and afiak they only used that for Concorde, but maybe I'm wrong. Anyway, nothing to do with OW, but this being a semi hotbed of aviation interests I thought some of you might be amused.
