S82-33394 (5 July 1982) --- A rare sight in Houston is the appearance of the spacecraft whose flights are monitored from that city, but with the brief stopover of Space Shuttle Challenger, thousands of area residents were afforded that opportunity as part of a nationwide special July 4 celebration. Here, the Challenger and its Shuttle Carrier Aircraft, NASA 905 (a modified Boeing 747 aircraft) are readied for the completion of the journey from California to Florida. The Columbia landed in California on July 4 (STS-4) and the Enterprise was already there, so three Shuttles were together as appropriate backdrops for a space-oriented July 4 speech by President Ronald Reagan. Crew for the NASA 905 for Challenger's Florida trip from Houston were Pilot Joseph S. Algranti, Co-Pilot Francis R. (Dick) Scobee.
