SpaceX's Starship didn't immediately respond to a self-destruct command

In a Twitter audio chat on Saturday, SpaceX's founder, Elon Musk, shared more details about what went awry during the first fully integrated Starship rocket and Super Heavy booster launch in April. One of the biggest revelations: The self-destruct setting took 40 seconds to work — a seemingly short time, except when you're uncertain if the massive rocket you just launched will blow up before hitting land. To recap the day's events, the rocket and booster cleared the launch pad before being unable to separate from each other, flipping and, finally, blowing up. The automated command should have immediately caused an explosion, but tumbled around for a bit first, The New York Times reported.
