Sounds from the Falcon Heavy launch

Behind the Black points us to a report of What the Falcon Heavy launch sounded like.

What a treat it must have been to watch from miles away.

Using special stereo mikes, the recording catches the clicks of many nearby cameras before being overwhelmed by the rocket sounds.

Listen carefully for the multiple sonic booms from the boosters returning to earth. Each booster gives off a boom from the engines, then the landing legs, and then the directional control arms. So 6 booms expected. Sound track wave form shows echos, but one overlapped, so there were 5 booms from each booster.

Astounding, all the way around.

Also Behind the Black provided Update on Falcon Heavy core stage landing failure.  Turns out that two of the three engines scheduled to fire, slowing the descent, did not do so. Core booster missed the landing barge by around 300 feet.

BtB says this is why one runs experiments. Find out what doesn’t work, figure out the reason, and fix it.
