Reminder: The *average* bolide impact velocity at Earth is 20 km/s. That's five seconds from the Kármán line to the ground. There's no slow movement of an asteroid through the sky, giving you enough time to say goodbye to your loved ones. One moment you're alive, the next you're on fire.

Grim though this is. It would happen so fast, your nerves would not have time to tell you, you're dying ... then dead.
