Oh for a time machine...
At Dunsfold in the 1980's, the Test Pilots held de-briefings on the weeks' projects & trials, on Friday afternoons straight after work.
The thing which put a spoke in this great idea was that most people travelled in shared lift syndicates in those days, so unless everyone in the car ( and their spouses ) agreed, it was a problem.
By pure luck I'd just decided that sharing a lift was a major pain ( there were enough stories there to fill a book, including the diabetic driver who took us up the runway one foggy morning ! ) so I was able to attend lectures by several T'P's at a time, including J.F, Taylor Scott, Heinz Frick, etc; the sort of experience money just can't buy...
As the attendances were embarassingly small the plan ran out of steam, but a great idea.
