Tons of ufos last night!?

So I was looking into the sky for a rocket launch, and the Xspæc team scrubbed it with less than 5 seconds left for the countdown!!!! That's almost UNHEARD OF! usually there are ~20 seconds to spare if the rocket even passes preliminary safety checks at all. SOOOO, right after that I saw a long stream of small green lights traveling NE, literally ducks in a row each dot only visible for a few seconds, and there were dozens of them! UuUntil eventually the stream stopped. Did anyone else see this?? These two events together has me pretty spooked honestly!!
