These are well supersonic in this video, and likely still hypersonic (they were definitely hypersonic at the initial stages of re-entry). Compare how fast these look compared to airliners, which are going 80+ percent of the speed of sound and look like they're crawling by comparison.

Gives the average person a good idea of the speeds we are talking about (Mach 5+) when talking about ballistic missiles in their terminal faze.
And hopefully a better idea of why ballistic missiles are a pain to intercept.
