time, and had to be ordered back into the spacecraft. While White was outside, a spare thermal glove floated away through the open hatch of the spacecraft, becoming an early piece of space debris in low Earth orbit, until it burned up upon re-entry into the Earth's atmosphere. There was a mechanical problem with the hatch mechanism, which made it difficult to open and to relatch. McDivitt was able to get the door locked by using his glove to push on the gears that controlled the mechanism. This added to the time constraint of the spacewalk and could have threatened the lives of both men if McDivitt had been unable to get the hatch latched, as they could not re-enter the atmosphere with an unsealed hatch. When they returned to Earth, the two astronauts found that they were now celebrities. President Lyndon B. Johnson came to Houston to congratulate them, and he promoted them to the rank of lieutenant colonel. Later that week they traveled to the White House where Johnson presented them the NASA Exceptional Service Medal. They were given a ticker tape parade in Chicago, and went to the 1965 Paris Air Show, where they met cosmonaut Yuri Gagarin. White's next assignment after Gemini 4 was as the backup for Gemini 7 command pilot Frank Borman, with Collins assigned as his pilot. He was also named the astronaut specialist for the flight control systems of the Apollo command module. Under the usual procedure of crew rotation in the Gemini program, White would have been in line for a second flight as the command pilot of Gemini 10 in July 1966, which would have made him the first of his group to fly twice. He instead would be selected for the Apollo I program. Apollo program In March 1966, White was selected as senior pilot (second seat) for the first crewed Apollo flight, designated AS-204. His fellow astronauts would be Command Pilot Virgil "Gus" Grissom, who had flown in space on the Mercury-Redstone 4 mission in 1961 and as commander of the Gemini 3 in 1965, and Pilot Roger Chaffee, who had yet to fly into space. The mission, which the men named Apollo 1 in June, was originally planned for late 1966 to coincide with the last Gemini mission, but the impracticality of making the Gemini capsule and systems compatible with Apollo and delays in the spacecraft development
