Safety Briefing
Engine wouldn't start on flight home yesterday. After several attempts to start decison was made to move us to an alternative aircraft. Both aircraft were the same type. We had had the safety briefing on the original aircraft. When we borded the new one the safety briefing was no more than a very short annoucment reminding us of (most of) the salient points. No video shown, no crew in the cabin waving arms about.
Now, I think most passengers appreciated that (we were then 2h30m late) but I'm intrigued how legal this. Should the crew have given a new, complete, safety briefing?
