At St louis (Gateway Jet Rally) we fly darn near everything off our runway with no problems at 42' X 600'. I have at least 45 flights on my F-4E as well as my Mig 15, F-86, F-80, Bandits, BobCats, KingCat, Maverick, and the only one I had trouble with was my first flight on my TamJets F-18 as it ran a little long only because I had it too nose heavy. Paul Blanchard has even flown his CJM F-104 there with no problems as long as it isnt 100 degrees. I think we just get use to what we have.
