Ive been flying with a .38 in the cockpit ever since I joined my present outfit 5 years ago. Wouldnt leave home without it. Great security blanket. Bit like wx radar: you realise how vulnerable you were before you had it. No I havent fired a shot in anger. Not yet.
Im dead against cockpit video-cameras because its predictable that bloodey management will misuse the thing in lieu of its original intent. Theyve done it with CVRs and you can bet your @rse theyll do the same with CCRs.
BTW safecockpit I didnt respond to your survey for the reasons FG outlined, and also I dont like talking to non-pilots on the subject. Nothing personal.
