Project Thunderbolt
Wednesday, September 28, 2005

This is a Frank Kosdon rocket. Two stage, O to M flight. The top speed was over mach 3.5, and altitude over 70,000 feet.

Here is the O-10,000 booster stage in operation, thats over 2,000 lbs of thrust for a few sec.

Here you have the end of the ballistic coast stage, over 50,000 feet the upper stage recovery took place. The tracking smoke and small orange clouds can be seen. While the exact altitude of recovery is not clear, this is probably over 10 miles up. A great flight, but actually pretty low altitude considering the power involved. 150,000 feet could have been done with a higher mass fraction system. But still a great one.

A Dr. K classic.
