later made to the cockpits of both LLRVs to better simulate the actual Lunar Module. These included the addition of the LM's three-axis hand controller and throttle. A Styrofoam cockpit enclosure was also added to simulate the pilot's restricted view in the LM. The final LLRV flight at FRC took place on November 30, 1966. In December 1966, vehicle #1 was shipped to Houston, followed by #2 in January 1967. During the preceding two years, a total of 198 flights of LLRV#1 and six flights of LLRV#2 had been flown without a serious accident. The first LLRV flight by Neil Armstrong was made in vehicle #1 on March 27, 1967 from its base at a corner of Ellington Air Force Base, the headquarters for Johnson Space Center's aircraft operations. Joe Algranti, chief of JSC's Aircraft Operations Division, and test pilot H.E. Ream also made flights that month. Both observed, as did Armstrong and the other astronauts, that if a serious control problem developed, the pilot had little choice but to eject, since the vehicle only operated to a maximum altitude of . On May 6, 1968, Armstrong was forced to use LLRV #1's ejection seat from about altitude after a control problem, and had about four seconds on his full parachute before landing on the ground unhurt. The accident investigation board found that the fuel for the vehicle's attitude control thrusters had run out and that high winds were a major factor. As a result, the decision was made by JSC management to terminate further LLRV flights, as the first LLTV was about to be shipped from Bell to Ellington to begin ground and flight testing. Lunar Landing Training Vehicle Negotiations between JSC and Bell Aerosystems for three LLTVs, an improved training version of the LLRV, were initiated in October 1966 and a $5.9 million contract for three vehicles was finally signed in March 1967. In June 1968, the first vehicle was delivered by Bell to Ellington to begin its ground and flight testing by JSC's Aircraft Operations Division (AOD). AOD's head, Joe Algranti, was the principal test pilot for its first flight in August 1968. Flight testing continued until December 8, when Algranti lost control during a flight to expand the vehicle's speed envelope. He managed to eject just three-fifths of a second before the vehicle hit the ground, the close call believed to be as a result of
