HOUSTON A historic NASA jumbo jet has been cleared for its final takeoff not into the air, but on a road trip through the streets of Houston to the site of its future exhibit.

The space agency's original Shuttle Carrier Aircraft (SCA), a modified Boeing 747 jetliner that for more than 30 years ferried NASA's now-retired orbiters across the country, will make the journey from Houston's Ellington Field to Space Center Houston, the official visitor center for the Johnson Space Center, over the course of two nights at the end of April.

"The BIG Move!" Space Center Houston officials wrote on Facebook. "The Shuttle Carrier Aircraft will start its move from Ellington Field to Space Center Houston on April 28." [How NASA Flies Space Shuttles on 747 Jets (Photos)]

To enable its transport, Boeing's Aircraft on Ground (AOG) team partially disassembled the jet, removing its vertical stabilizer (or tail), aft section, engine mounts, and landing gear. The engineers also removed the jet's wings, marking the first time in history that the Boeing team separated a 747 from its wings outside of an aircraft hangar.

The work to take apart the SCA, which is also referred to by its tail number N905NA, or NASA 905 for short, began in mid-February and was finished Wednesday (March 26).

The SCA's fuselage, wings, aft section and other parts will next be loaded on to flatbed transports and trucks for the trip to Space Center Houston.

"To minimize the impact on traffic and local businesses, the move will occur over two nights starting at 9:00 p.m. [CDT]," the center's officials said.

Details of the move and where the public can view it as it happens will be announced soon, but the general plan is to traverse the 8 miles (13 kilometers) over the course of two legs.

On the first night, the convoy will travel from Ellington on Texas State Highway 3 to a staging area on E. Commerce Street, where the aircraft will spend the day (April 29). As night falls, the SCA will continue its trip to Space Center Houston, traveling along NASA Parkway (NASA Road 1).

"The convoy is then expected to arrive early Wednesday morning [April 30]," Space Center Houston officials said.
