Boeing is known for airplanes, but they actually have a long history in space. since nasa's beginning, boeing has been a contractor on every manned space program, including building the parts for the international space station. boeing has been in human space flight from day one and so she's part of our core. nasa is hosting a competition for private enterprise to build the spacecraft to transport humans to the international space station. winning this contract would cement dominance in the new space race. we see this as just the next huge opportunity for boeing and for nasa. how big do you expect the market to be? the development price itself is such a huge barrier; just a very different business model than boeing used to. our huge development programs are typically centered around commercial airplanes, military aircraft, where there is a lot of orders. and right now the foundation of the business is two flights a year.
