A gigantic piece of space history is set to splash down at Seattle's Museum of Flight on Saturday.
Although the Space Shuttle Trainer has never left the earth's atmosphere, museum officials say Seattle has won the biggest prize in the competition to show and explain this period in NASA history.
Visitors won't just get to look at the space artifact arriving this weekend, they will be able to climb aboard.
The full-scale plywood mock-up looks like a space shuttle without wings. The payload bay is scheduled to arrive in two pieces in July and August and a mock-up of the engine section is being assembled locally.
The shuttle trainer was used by every astronaut to ever fly aboard a space shuttle.
