      Also one out of three chance you’ll need swim trunks. Hopefully one that doubles as a VERY LARGE airbag.

      He's been doing better than that on the single-sticks. I bet he could beat out Blue and Virgin for the suborbital market with minimal investment if he wanted to

      (just put a dummy stage 2 on a Falcon 9/Dragon and you're done)

      That would be a pricey suborbital ride.

      Fair enough. Finances not my strong point :-). Just a bare stage 1, with a person in a pressure suit clinging on, how much would that cost?

      F9 is $62 million. You’d save a bit w/o second stage but then you’d have to add the cost of duct taping the person to the booster.

      What about a hollow 2nd stage. Windows galore. How many seats could you get on that? $62 million could come down quickly.

      Right. Stick 60 people into a hollow glass cylinder. That’s be $1 mill each. You’d need 600 passengers to get it down to the $100K price pt. With no escape system.

      It was 62 million for throw-away stages. Fully reusables will knock that down. (Fuel is under 500K per launch.) And BFR will be designed for people from getgo, offer fully orbital flights (free fall is free) and be its own escape system.

      When SpaceX cuts its price of orbital F9 launches to single digit millions, then you have a pt. But that isn’t now. The original premise was that SpaceX could do a few tweaks to the F9 and beat VG and Blue in the suborbital space tourism biz.
