Yep. You need to leave 100 km altitude at a 38* angle, going 4826 m/sec. Gravity and drag losses will take the total somewhere north of 6000 m/sec, then add landing fuel if you're doing a VTVL. -R -- "We've all heard that a million monkeys banging on a million typewriters will eventually reproduce the entire works of Shakespeare.
