As it turns out, it's pretty bad: we could make it in about 25 minutes on Space Shuttle... if at all . In the process, we would also travel ~520 miles *away* from SF first, before turning around. In other words, the trip would take us over Baja California, Mexico, or just short of Salt Lake City, UT, or just short of Portland, OR -- before returning to SF. It would also take us ~410,000 feet up before starting down. That's high. No way to make it shorter or faster though -- gotta burn that fuel. Otherwise, it would take exactly two minutes from stand-still in Mountain View to overflying Exploratorium 30 miles away -- at 148,000 feet, moving at 3000 MPH .
