My friend and i were in an industrial area of the city when we saw something we couldn't explain. in the distance ahead of us just above the horizon was something our brains saw but we're having a hard time identifying. at first we thought it could have been a bird, but it was way too fast to be a bird. then we noticed the lights. red lights long and thin like florescent light bulbs in pairs at the tips of a triangle shape. as the lights passed in front of a building in the distance we noticed that in between the lights looked like the predator suit camouflage. transparent but blurry/wavy. it happened so fast and we were both so confused about what we were seeing neither of us thought to pull out our phones and get pictures. afterward i (*half) jokingly said to my friend and proclaimed to the sky "that was awesome sure would be cool if they decided to come back again" and we continued walking. and wouldn't you know it, about 2-5 mins later here it came again this time from relatively the opposite direction! too fast to be a bird, too low to be a plane. absolutely silent. and as quickly as it reappeared, it was gone.
