Check out an AMRAAM or Harpoon for reference, not a space craft.

Neither has a ‘boost’ phase, Harpoon is subsonic, AMRAAM isn’t staged. ICBMs do.

yes but neither are fired from underwater, the point of the Shuttle video was that even at distance of only 3 miles away the rocket was in the frame for more than a minute,

and you can clearly see in the blown up image from the article you cited that it is a missile, so you are welcome to believe what some random author told you to believe and it was a "helicopter" I can make up my own mind.

and here is a long exposure of the space shuttle taking off

and here is a long exposure of a helicopter

I can see why the 'expert' was confused...

from the article you posted:

"This was actually taken with "Cam4", which is a little wider angle than Cam2 and pointing in the same direction."

and

"It is a Canon T3 Rebel set up as a webcam. Images are captured about every 40-45 seconds. 3.5/20 second exposure/ 1600iso. I only run it on clear nights or when there could be severe weather."

so see where it says 3.5/20 that means the wider angle was a 3 to 5 ratio and exposed for 20 seconds, so instead of the angle I posted earlier which was a 1 to 1 ratio and at 10 feet from the lens it had a 10 ft field of view this particular camera would have a 50 ft field of view 30 feet from the lens or if 3 miles away it would be five miles wide and an even greater distance to travel before leaving the frame than I had previously speculated.
