I guess I've seen a few things in the sky at night that were "unidentifiable". I can;t articulate them though.

I saw lightening strike an object within 150 yards of me....twice. Once I watched, heard, and felt it strike a large rock just off the side of the highway in Capitan, NM. I mean: I saw the bolt strike the rock! If I had to describe the sound I might be tempted to say it sounded like a 30-06 going off within a few feet of someone, yet without the extended or lingering crack of a rifle as the bullet travels away. It scared the hell out of my friend and I.

Once I saw lightening strike the headlight of a car on I-20 west of Midland, Texas. I was eastbound and the "victim" was westbound....probably less than 100 feet away. It was a late summer afternoon...no evening, but still light. I swear to this day that the car stopped for a millisecond, then continued. Yes, yes I know. The car is grounded by its tires. I saw and heard this happen. This one I didn;t "feel" though. My window was down and there were no obstructions in the way. It was eerie.
