We went outside in our Orlando office to see the flair up in the sky, and then were looking for the re-entry, by the time we could figure out where it was our coworker said it was already standing upright.

I was at Canaveral for the double booster return (Heavy?), and it's unbelievable the velocity those things come back down at, with the powered deceleration.

A few seconds after the sonic boom, you're seeing them cancel out the last of their velocity and land on the pad.

One of those 'it can't possibly be that big because nothing that big could be moving that fast' optical lack of reference moments.
