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.

These are going slow actually, they'd be much faster ay Mach 5. These are slow and on fire, no sonic boom
