Pioneering space tourism company depends on clients to create buzz, AP
"More than 60,000 people have registered to fly with Virgin Galactic since 2004, but only about 200 have paid full or partial deposits totaling about $16.4 million, according to the company. That money is refundable if flights, which would have six passengers and two crew, never take off. Its competitor, Virginia-based Space Adventures, which brokered three tourist flights to the international space station, has more than 200 reservations, but only $3 million in escrow. Oklahoma-based Rocketplane Kistler declined to disclose sales figures."
