getting closer to space tourism-clarence

Richard and Burt had invented a space craft to take tourist to space for $300,000.There are two challenges to building the craft. first they have to go to space cheaply as rockets use too many fuels.So a mother ship called white knight will bring the space ship up and out of the earth atmosphereand launch the space ship.the space ship will then use its rocket to blast it higher.when it reach an attitude of 110 the fuel will burn out.the other challenge is coming down safely so the space ship will change into feather position.At 21.5km the space ship will change into glider mode and glide down to earth safely.
