10 seconds of bliss
The hot fire demo started at around 4:14 p.m. ET and lasted for roughly 10 seconds. On Twitter, SpaceX later said the test lasted for the “full duration.” But as Musk pointed out in a subsequent tweet, the team turned off one engine prior to the mass ignition and one engine stopped itself, meaning that 31 of the 33 engines fired overall. “But still enough engines to reach orbit!” Musk exclaimed. Fair point, but in my books the test was incomplete and not a total success.
