You may be used to Boeing jetting you off across the world but now the company is aiming to take people into space.
Two were strapped into the model on Monday demonstrate the craft
The only thing missing from the model is a toilet.
Tony Castilleja, a Boeing CST-100 mechanical engineer, told collectSPACE.com: "We have a couple of options.
"It is all about reducing mass, so we do not have a true space toilet like shuttle did because we just don't have the room in this vehicle.
"But there are some design alternatives that we're looking at, from diapers to mechanical devices."
Boeing is in competition with Space X and Sierra Nevada to win a Nasa contract to take astronauts into orbit.

Since the retiring of its space fleet, Nasa has been paying Russia a small fortune to do the job for them - £41 million a seat.
Boeing is no stranger to building space equipment.
They built the Saturn V S-IC first stage, and designed and built the lunar roving vehicle that was used on Apollo missions 15 through 17.
