Wouldent it be a much smaller technical risk if one built 10 more DC-1
wehicels instead and stream lined the fuel flights?
It ought to be cheaper but I havent got reliable figurs.
I think it makes sence to use standard DC-1 wehicels for simple high volume
cargo until there is enough flights to justify a gas gun that launches
smal cannisters for a much lover cost per kilogram to orbit.
