Not that this matters much but I used to do a ton of photoshop work down to the pixel and would manually refocus my eyes to clear them. I felt like Wally doing this 3 or 4 times trying to gauge the altitude. It was definitely above the cloud level. I put it around normal cruising altitude of a commercial jet but at that altitude it had to be the size of an aircraft carrier because of spacing of the lights. After talking to several people about this others suggested it was much lower than I described because of the flight characteristics, but I guarantee we didn't get buzzed by this thing; it was miles away.
