YOU MUST BE A BRITISH AIRWAYS LAWYER FOR SAYING THE DIRTY SOCKS IS NOTHING TO DO WITH OIL!!
Obviously you've been in for your sense of humour bypass
Seems every time someone on here says something that's not liked they get accused of being a lawyer or a reporter. I'm neither.
I hope the industry gets to the bottom of this as i am one of the unfortunates who has to spend long periods in the f/d looking for the source of these smells. Invariably they (on the 757) don't re-occur on ground runs but we have in the past replaced engines and APU's. Don't know if the cabin being pressurised has any bearing on how concentrated the smells become.
***Uncle Sam Flies - Step on virtually any BA 757 with just ground power on and you'll get where I was coming from in my last post - they're not exactly a bed of roses!!***
