(For those of you who haven't seen any of my posts in the past, I have a morbid fascination with plane crashes.) Yesterday, June 1st, I was observing Air Show Colorado from the balcony of my apartment via binoculars. Air Show Colorado was taking place at Jefferson County Airport, which is one of the highest points in north Denver. The airport is only about three miles northwest of my apartment so I had a great view. I took a quick break from watching to take a shower (after all, it was late, late morning and I was on my balcony in pajamas) and then went back to watching. The plane that was in the air wasn't really doing anything so I stepped away for about five minutes to dry my hair. As I was walking back to the balcony, I started to hear sirens. I looked out the window and saw a big cloud of smoke rising from the direction of the airport so I went out with the binoculars. I could see the rescue equipment hauling tail off of the runway and down a hill and through the grass toward a large building which appeared to be on fire. I joked with my husband that maybe a plane crashed. So as I kept watching, he turned on the TV just in time to hear a report about a plane crash at Air Show Colorado, just southeast of the airport. I missed seeing a real live plane crash by no more than 10 SECONDS!!!!! I've figured out the time by watching the news footage of the crash. The big dark cloud of smoke started to rise immediately after the fireball subsided and there wasn't that much smoke when I first saw it. I can't believe I missed seeing a plane crash by seconds. Anyway, I just wanted to give some background on the crash before I asked a question. They interviewed some pilots who said that the high temperature caused the ambient altitude to climb by almost 3,000 feet. (It was in the mid-80's and the airport is at ~5700 feet). I was wondering exactly how this affects the performance of the aircraft. Specifically during stunts, how much higher do planes have to climb during conditions like this in order to do a 360?
