You proved you don't panic, and that's the most dangerous reaction ... closely followed by complacency. As for being relaxed ...
I think I must be slightly strange? ... either that or it's just dulled senses? I'm very relaxed when flying, but not always when thinking about it. When things go wrong or there's a strange noise I seem to react rather indifferently? It's the same in my day to day life; if for example, a load bang wakes me and SWMBO at night ( no no, not THAT kind of bang
) her reaction is fright, mine is .... lay there and analysis what it could be and once decided, go back to sleep!
I've had a couple of engine failures, and had military jets fly under me at 300' on finals in a glider! In these circumstances I felt quite relaxed (which must be odd ) and actually enjoyed the challenge of flying out of trouble.
Having said all that I do get anxious before flying if it's been a while .... but never during.
