... 60 kilometers per second is an amazing speed. The setting against the Milky Way is a beautiful sight.
Kinetic Energy of a perseid the size of a basketball is phenomenal...
ENERGY = 1/2 * mass * velocity ^2
ENERGY = 1/2 * 100 lbs * 60 km/s ^2
19.514 tons TNT
... an 18" rock is about 300 lbs and would yield a nearly 60 ton TNT explosion at this incredible speed.
... a 3 foot by 4 foot rock will weigh in at about 5000 lbs and at this speed would result in nearly a 1 kiloton explosion. (suitcase nuclear)

I went out for an hour that night and saw 8. I thought that was pretty good. A couple of them looked like that.

Years ago while watching the Perseids, I heard one "sizzle" in the atmosphere. It was really cool.
