I cannot tell you a precise date other than school year 1996 or 97. We were having a NJROTC parents meeting at PAHS. Some of us stepped outside, 8 pm-ish. I was facing the sky; others the building. I saw what looked like something round and fuzzy at the distance. It flew left to right across the sky, made an extremely sharp left turn, continued for a second, made another extremely sharp right turn, and after another second or two, completely vanished. I don't think any country on earth has technology like that... yet, or we would know... wouldn't we.
