Cool video of the landing with double-tripple sonic booms.
“[The] first boom is from the aft end (engines),” said John Taylor, SpaceX’s Communications Director. “[The] second boom is from the landing legs at the widest point going up the side of the rocket. [The] third boom is from the fins near the forward end.”
This one is from farther away. It is amazing how long after they have landed that the booms arrive.
