Is achievingorbit that easy?

[jacobmuller]

I was doodling an SM+3 design for a reentry* vehicle using Spaceships when the possibility of using it for relaunch occured to me.

Basically, reentry capable only, would be 1 armour, control in both cores for one crew, 3 passenger seats (15 spaces), a soft-landing system and a combined fuel/power and drive section to achieve de-orbit.

But, if you replace 2 passengers with fuel tankage, a streamlined winged design can achieve orbit in a couple** of minutes? I must be doing the arith wrong...

*emergency, sport or military stealth unit.
**eg 2/3 g for approximately 2 minutes.
PS: I understand Spaceships is less accurae below SM+5 but it's not likely I'll be making any reentry vehicles.
PPS: you could replace passenger seats with hibernation or nanostasis modules and travel around waiting for rescue.
