I don't think if makes sense to decelerate from Mach 30 using parachutes.

To your second point, if you watch the video, you can see the booster descending under power, without parachutes.

Even if it did, it would be more of a drag chute rather than a parachute. The Mach 30 velocity of orbit is horizontal to the ground, not downwards.

I think klunger is referring to the Blue Origin which is deigned to take tourists to the edge of space and then come down, not to go anywhere near Mach 30. https://en.wikipedia.org/wiki/Blue_Origin_New_Shepard#Missio...
