'Panic' and the P.I.C.
IMHO you'll be hard pressed to find much reference to 'panic' in professional pilots, especially not once they are into the 3000+ hrs level. My experience is that the pro is so focussed on the emergency that there's no time for other reactions.
I would suggest that you look into interviewing pilots who have survived the following:
* totally lost in inland Australia or similar
* VFR and stuck on top,necessitating assistance
* Inadvertant IMC while VFR
It might be that none of these 'panic'd' either, which is why they are still here to tell their story?
