I was sleeping on my flight and randomly woke up and looked out the window. i saw an orb..At first i was thinking it was another plane until the type of flying i saw...It was going up and down way too fast and kept going black then showing up again. next i saw 2 others appear next to it. they followed for about 20 mins....I also saw at this time one zoom up to space and that one was white (starlike) then proceeded to see 2 others do the same..( the same thing that was discovered on the nasa tapes and they tried to say it was debri or something they also have videos on youtube that say people thought it was an angel) i knew they were ufos. i dont know if anyone else saw..I was the only one looking out the window due to our high altitude and it being nighttime no one has the urge to look out of the window at that time.
