I would say it would be getting NASA to recreate a Mercury capsule and Atlas rocket. That can land in the middle of the ocean, and they went three times around the Earth in about 5 hours. So, the journey would probably take you on the order of two to two an a half hours.
Of course, that is assuming you had everything arranged ahead of time rather than the decade or two it would take to get the thing together.
Knowing the airlines these days, I wouldn’t expect to spend much more time on the launchpad that you would at the airport.
The OP didn’t say “fastest available transport,” just “how long.” So since e has an infinite amount of money and has bribed everybody necessary, e may as well travel in high style aboard USAF Air Force One.
Couldn’t he just pay the Russians for a ride? I’m not sure what’s on the opposite side of the Earth from where they launch but I think that they can plop that thing down in most places.
Yep, SR71 or some supersonic fighter, inflight refuelling, hit the ejector seat as you go over the destination area, job done and in moderate comfort. Prepping a space vehicle for launch takes days, if not weeks. Something like 250,000 man-hours to get the space shuttle ready, IIRC.
