Lunar Flag Assembly flag, placed about from the centerline of the "Eagle" landing craft, was blown over by the blast of the rocket exhaust during takeoff. Because of this, care was taken by subsequent crews to place the flags at greater distances from the Lunar Module. The landing on Apollo 13 was aborted due to a major spacecraft malfunction encountered before reaching the Moon. The flag carried on that flight was destroyed with the Lunar Module "Aquarius" when it reentered the Earth's atmosphere. A review of photographs taken by the Lunar Reconnaissance Orbiter (LRO) indicates that flags placed during the Apollo 12, Apollo
Apollo 7 for 21 months, while the cause of the accident was investigated and improvements made to the spacecraft and safety procedures, and unmanned test flights of the Saturn V rocket and Apollo Lunar Module were made. Apollo 7 fulfilled Apollo 1's mission of testing the Apollo command and service module (CSM) in low Earth orbit. The Apollo 7 crew was commanded by Walter M. Schirra, with senior pilot / navigator Donn F. Eisele, and pilot / systems engineer R. Walter Cunningham. Official crew titles were made consistent with those that would be used for the manned lunar landing missions: Eisele was
