Challenged by Space Adventures (which negotiated Dennis Tito’s flight to the space station) to create a launch vehicle capable of three flights daily, Myasishchev Design Bureau has responded with the Cosmopolis XXI Aerospace System. The three-passenger module would piggyback on an airplane to the upper atmosphere before a rocket delivered

it to its 62-mile-high cruising altitude. First flights are planned for 2005, at a price of $98,000 per seat.
