White Objects flying during the Space Shuttle Challenger 1/28/1986

I believe these objest are of UFOs.
It is a film of the  Space Shuttle Challenger  launch and it is on   YouTube.
The title of it is: Teacher in Space backup watches Space Shuttle Challenger.
 You need to watch very closely at this film. You need to know what to look for.
There is a white object in the film. It is seen several times. It is left of the smoke or steam.
Watch when the girl moves from her spot and and then you will see an object moving left. It may seem maybe like a flash of light. Just keep following it.
Using the little timer at 1:03 there is a white object in top left corner.  At 1:51 you see it almost in the middle of the screen.  At 1;54 you see it has move more to the left.  At 2:12 you see the object better. Between 2:13 and 2:16 it is moving west, makes like a swoop and the travels upward.
Anyway, just take a look at it and watch it several times if you have to.
