Ablation ceases at 3-4 km/s (about Mach 10), and this is about where the
meteoroid becomes invisible. For a typical meteorite, it will rapidly lose
this remaining velocity and enter nearly vertical dark flight.

Subject: Re: [meteorite-list] Fireball question / sonic boom
George jut brought up a good point and I have a question. The speed of
sound is about 760 MPH.
What is the speed at which a meteoroid extinguishes and is no longer
incandescent?
Regards,
Eric
