Thanks for the helpful input on Volvos guys, very useful and informative I'm sure...
The question I asked was about Boeings though, machines several orders up the food-chain from nasty boring Swedish cars.
I have searched the search engines and search facility here and come up with nothing, so please, if you have a lead, please be kind enough to pass on some real info, rather than smug suggestions about where I might look once again in vain!
