Ja, I meant 12,000 m/sec. If they can get 5000 sec or about 50k m/sec, then
well OK, I will at least pay attention.
There was a guy named Bruce Johnson at NASA Glenn in Ohio back in the 90s
who was saying we could make those kinds of numbers, but they were a long
way from a flight version.
Gene you surprise me man! You let me off easy on that 1200 goof. You are
getting soft in our old age pal.
