I found all of the above interesting as I had not really thought about ejection seats in such detail previously. When a seat is described as zero-zero I hadn't considered what that really meant.
So, given all of that there must logically be issues with the crew members weight. Would I be right in thinking that if a pilot is over a certain weight the ejection would not be "clean", also if the pilot was small and light then would that not be a problem too?
Normally, I would not ask but as some of you are in a mood to educate I thought I might take advantage
