Joke for the day;
While undergoing one of these procedures, one of our F/O's asked the 'examiner' if he'd be allowed to have an axe on board with a blade on one side and a point on the other. The guy had a fit and said that it would be absolutely forbidden!! "Then, why am I sitting within a couple of feet of one for the next 11 hours?" was the reply!
Especially in the US, when one is sealed in behind a door, these crew checks are a public farce!!
G'day
