Very slow no sound low altitude seen about 1 am I saw it 1st then got everyone else to watch it flew in straight line for long distance

Had lights no green or red no strobes no flashing just multiple either boomerang or triangle very clear night no clouds no sound wasn't a blimp or any aircraft I've ever seen and I've seen most about 20 miles from Redstone arsenal outside Huntsville al.it came from the east moved west just high enough to clear the mountains watched it for atleast 15 to 20 minutes speed maybe 15 to 20 mph about 15 or more people watching it no body could tell what it was but every one new what it wasn't any kind of aircraft we've seen before or since everyone was amazed I've told people about it my whole life. I seen one other thing can't explain we were watching for shooting stars me and my daughter we were facing east I seen what I thought was a jet at high altitude about 7 years later it light moving from north to south not a satellite thought it was a jet seen it for several minutes until it got from one side of sky to other just a white light very high in sky moving about speed of jet until it just stops sitting for few seconds then suddenly it shoots straight up at unbelievable speed then disappeared in seconds wasn't a shooting star because we watched it for about minute or two before it stopped then straight up .I've only seen 2 things I couldn't explain I could just tell they didn't seem like we made those or could do that plus I seen both with other witnesses they were both amazing to see I didn't know if ufo ever existed till I seen both of those just didn't seem natural wish I would took videos to prove what we seen.but I'll always remember what we saw.they can't hide it or lie forever atleast there showing jet fighter videos now and admitting there's something out there that they don't know what it is .I'm glad I got to see these 2 different times with other people.
