FlyingForFun: Yes you are right it is probably just that I have not seen many large aircraft up close and the fact that it came from above and behind means that it just popped in to my windscreen and it was going fast means that it was unexpected.. .We have all spotted other aircraft and been surprised but this one just seemed bigger than most and because I could not see it until it had already reached the closest point it was a bit of a shock. . .. .I have jumped from many C130's in the past but in freefall the aircraft gets pretty small rather quickly.. .. .The comments made on here have helped me to think it through and put it all in to perspective. With my limited experience of 64 hours as P1 <a href="http://www.bishopsgateoffice.com/Gary/LogBook/LogBook001.asp" target="_blank">View Logbook</a> I thought I would ask for some views of more experienced people and it has helped.
