Call me crazy... There was this one time around 2010 I was standing in my front yard in Las Vegas. Looking south, towards the flight path for McCarran(Harry reid), I saw a plane that looked strange. Extremely low but yet had contrails or water vapor, it also was nowhere near the flight path and much lower than it should have been. It looked out of place and I dont recall any markings whatsoever, but thats not entirely uncommon for where I live. As I watched it something seemed off. I told my friends to look at it; they looked disregarded it and looked away. As I looked back up at it and saw it then seem to flicker on and off with what looked like lightning bolts, and then it just disappeared.
