There were multiple objects that hovered and accelerated at lightning fast speed.

we were in our early teens in a local park around 2 am when i observed a small light over the mountains. shortly after 3 then 4 then another appeared.We sat motionless for awhile and observed what we thought to be airplanes and then helecopters as we then noticed they were not moving. These lights were small dots along the horizon in a random formation and accelerating rapidlly and comming to an abrupt stop! This would go on intermitanlly for about 10-15 min.We all knew that these objects could'nt have been created by any earthly technology.We stood around mezmorized, our eyes fixated at these objects when all of a sudden, one by one, they accelerated like a blink of light out of the atmosphere and into space.We were later informed that Rocketdyne, where they test the shuttle engines, was up on that same mountain top. PS. this story is not made up! Yhis really happened.
