On Kauai, red then green glowing object falls from sky only 50 yards away from 250 feet upWe were at the Embassy Suites/The Point resort hotel on Kaua’i. My girlfriend’s son (13 yrs. old) and I (44 yrs. old) were facing northeast, talking. Our friend (35 yrs. old) was in the pool, facing northeast, talking to my girlfriend who was facing the rest of us, southwest. It was about 9:30pm or 10pm. This was July 18th.My girlfriends son and I were facing my girlfriend and our other friend who were in the pool. The pool is surrounded by condos and palm trees. As we were all talking, I saw a neon glowing, oblong object "fall" from about 500 feet or less at a 45 degree angle, right over the building and palm trees, from right to left. The object was about 50 yards away from us. It disappeared behind the building. Two of the others saw the same thing, except for them, it started out as a red object that turned green. I thought I saw yellow inside the green and a black dot inside the yellow.The funny thing is, there wasn’t a trail behind this object and it didn’t make any noise coming down and didn’t seem to crash into anything. The size was very hard to determine. It could have been the size of a basketball or it could have been the size of a small car.Nothing went up in the sky, like a flare. No sound was heard from it. No sparks. Just a closed looped, oblong shaped, red, then green/yellow/black object.We weren’t drinking or anything else. No missile testing. Three of us saw it. I’ve never seen a “u.f.o.” before, neither had the others.
