As for daft questions:
Picture this, very respected, very well spoken ex BA 747 Flight Engineer teaching pressurisation and aircon at a ground school thats now skint.
For nearly four days the guy is going on about low and high pressure bleeds from the BRT, imagine all students frantically looking through their notes and index's for any mention of BRT!
BRT this, BRT that, for four full days.
Cause of massive discussion at lunchtime and over coffee, nobody wants to ask even though we are all desperate to know.
On the last day somebody asks the question
"Big round thing" comes the reply in this wonderful BA accent - whole class was pissing themselves for hours !!
