HOUSTON -

A modified jumbo jet that transported shuttles piggyback to Florida following flights has arrived at its new home in Texas after an 8-mile highway trek.

What was known as the Shuttle Carrier Aircraft, or SCA, reached Space Center Houston after a slow-moving trip from Ellington Field.

Some giant flatbed trailers on Monday began hauling the biggest disassembled pieces of the old 747 jumbo jet that flew shuttles on cross-country trips. The entourage arrived at Space Center Houston late Tuesday night.

The jet will be put together and topped with a shuttle replica about 60 feet off the ground as a museum piece. The site is expected to open next year just outside NASA's Johnson Space Center.

Mission Control in Houston served as the center for the nation's manned space flights.
