This aircraft looks like a BA plane too but it 'aint. Check the reg.
ZS-OTG - British Airways (Comair) Boeing 737-400 Aircraft @ Airplane-Pictures.net
To reiterate, Openskies has a French AOC, flies from France to the 'States and has no BA pilots, trainers or managers. BA pilots would rather the chatham flag wasn't on the fin and you can read all about that using this forums search function.
Certain elements of this forum and the media would love this to have been a BA plane but it just plain isn't, in the same way that the Continental Dash-8 crash in Buffalo a while back was actually Colgan Air operating under a codeshare agreement. The fact it was painted in Continental colours meant that Continental got the bad press in the media and I suspect most mainline Continental flightcrew would argue their training and experience levels are somewhat different.
Just my two pennies' worth.
