I was heading towards Cave Creek Az.from Phoenix Az. On the 202 east. Noticed something in sky, there were acyually two things in sky, one was long but I focused on the smaller one because it was closer. So I kept noticing it as I drove and it didnt move and I couldnt make out any shape. I finally pulled over and tried to take pic with my crappy phone, nothin but a small blur. I called my girlfriend and told her. I got back on freeway and kept watching it, it started changing into a long cylinder shape and then to a point, as this was going on, it started leaving a wide contrail. The trail got longer and it looked like it was going straight up. I could almost make out a shape but I was going down the freeway and had to watch the road. I noticed a flashing light and it was going out of view due to my position, so I got off at Val Vista exit and pulled over in a parking lot. It was gone......when I got to my destination (walmart in queen creek) and completed my job, I saw two blackhawk helicopters. When I was driving back I saw another blackhawk. Did anybody else see this????
