SOE, one can always find the odd example, but it has to be measured against the millions of jumpseat rides that took place before 911. Strangely enough you don't quote those examples where company personnel were riding jumpseat (Fedex and PSA to name two). What you may not appreciate is that for 50 years the use of jumpseats was as common as muck and in all that time there were very very few incidents. No matter what knee jerk solutions the authorities come up with, you're no safer flying today than I was when I was 28.
