a mission patch with the name Apollo1 (though the approval was subsequently withdrawn pending a final decision on the mission designation, which was not resolved until after the fire). The design's center depicts a command and service module flying over the southeastern United States with Florida (the launch point) prominent. The Moon is seen in the distance, symbolic of the eventual program goal. A yellow border carries the mission and astronaut names with another border set with stars and stripes, trimmed in gold. The insignia was designed by the crew, with the artwork done by North American Aviation employee Allen Stevens. Spacecraft and crew preparation The Apollo command and service module was much bigger and far more complex than any previous manned spacecraft. In October 1963, Joseph F. Shea was named Apollo Spacecraft Program Office (ASPO) manager, responsible for managing the design and construction of both the CSM and the LM. In a spacecraft review meeting held with Shea on August 19, 1966 (a week before delivery), the crew expressed concern about the amount of flammable material (mainly nylon netting and Velcro) in the cabin, which both astronauts and technicians found convenient for holding tools and equipment in place. Although Shea gave the spacecraft a passing grade, after the meeting they gave him a crew portrait they had posed with heads bowed and hands clasped in prayer, with the inscription: Shea gave his staff orders to tell North American to remove the flammables from the cabin, but did not supervise the issue personally. North American shipped spacecraft CM-012 to Kennedy Space Center on August 26, 1966, under a conditional Certificate of Flight Worthiness: 113 significant incomplete planned engineering changes had to be completed at KSC. That was not all; an additional 623 engineering change orders were made and completed after delivery. Grissom became so frustrated with the inability of the training simulator engineers to keep up with the spacecraft changes that he took a lemon from a tree by his house and hung it on the simulator. The command and service modules were mated in the KSC altitude chamber in September, and combined system testing was performed. Altitude testing was performed first uncrewed, then with both the prime and backup crews, from October 10 through December 30. During this testing, the environmental control unit in the command module was found to have a design flaw, and was sent back to
