Hi All, Interesting pictures Marshall. Good camera. Can`t tell what kind of aircraft they are,as matter of fact cannot see the aircraft. Not tankers or commercial, as I see only one contrail, that means only one engine. Each engine will leave a contrail. Single engine fighters or two engines very close together. Generally commercial aircraft will not leave a contrail, flying to slow. Your pictures are high speed military aircraft. If conditions are right, all aircraft will leave contrails. I have seen with my own eyes contrails from aircraft taking off of aircraft carriers. Even the prop tips of propeller aircraft will leave a contrail. Have seen many many fighter aircraft leaving contrails during low altitude strafing runs. The fan on my car made a contrail a few times on cool humid days when I rev`ed up the engine during maintenance work on it. Engines will create contrails before the wings do. The low vapor pressure at the wing tips have only the water vapor in the air to work on, where as the engines (jet or recip) produce large quanties of water during combustion. All combustion produces water vapor. Even a candle, just hold a chilled pane of glass over a candle and watch it load up with water drops when over the candle. Hold your hand behind the car tailpipe and watch it get wet when you run the engine. All the trails in your pictures were ordinary vapor trails of high speed aircraft. I have looked at vapor trails for twenty five years as a military aviator. No mil or commercial aircraft operators are dumping anything. Sometimes a plane will dump fuel if they are over weight when arriving at their destination. Most of the time they are not over weight and do not dump anything. They are very conscious of fuel costs ( the major expense of aircraft operation) and go to great pains not to waste fuel. In all the flight operations I was involved with we were wery conservative with our fuel. It was usually in short supply and not to be wasted. Only in emergencies could it be dumped. The violet thing in your pictures looks like the day moon viewed through stratus translucidus air layers. Re: Field Guide to North American Weather,1997. Contrails are produced in nearly saturated air conditions near or cooler than freezing. As I said earlyer I have seen prop tips make contrails at 80f at sea and saturated air. EDB is not making your family sick. Find the real cause. Do some real investigation. This was well covered last year on this list. I am reposting that info. I`m pleased that your CS is keeping you all healthy, thats good.
