no training
back before it was common, I was a 'crab' on the old Invincible for several months.
The call came on a Friday night (doesn't it always?) "They want you on Invincible in the Adriatic on Monday Morning."
after the inevitable "Okay who is this?" the ball started rolling and by Wednesday I was on the ship. I had never been to sea before and it was bewildering to say the least.
We did have a minor fire, the lining in the funnel (or chimney as I called it) caught fire and I was asked to monitor the temperature of the wall (bulkhead) in my room (flat). I learn quickly and I'm sure I was no particular hazard to myself or others however ...
the language barrier frequently got in the way.
We take it for granted that we speak in 'RAF English' and when faced with an alien environment in which 'jackspeak' is the norm confusion is rife.
More joint exercises will no doubt help with this ...
