Oh I agree that this was a terrible thing. We bought a DC-3 and just after the purchase, the boss, not a pilot at all, was allowed to get into the left seat while we were flying.
And we were all killed instantly. Had a hell of a funeral though.
All of us were killed again when he sat in the left seat of our new Falcon 50EX and then again in the new Falcon 900EX while we where in flight.
Oh shoot, I forgot the time we were all killed when I let a very good looking female TV reporter sit in the right seat of a 727 I was flying.
Some people need to get a life.
