This is meant as a serious "tech" question from an ancient engineer
(a) I have an affinity with that class of folk who might be described as ancient engineers .. (olde pharts between ourselves ....)
(b) it doesn't have to be terribly related to flying to be OK for tech log .. main thing is it needs to be of interest to (at least some of) the assembled folk ...
(c) my favourite not terribly related to flying
thread had to do with Chinese cryptography ... I guess that we could figure out some relevance to flying over an ale ... perhaps ... and I figure that's enough justification to leave it run ....
... I thought that the thread was fascinating .... it really is amazing what one can learn from the incredibly catholic wealth of knowledge represented by the assembled PPRuNe fraternity ...
(d) coke cans ? .. some pilots drink Coke ... close enough for me ...
