The question of whether a data tape recorder would be installed on LEM-1 had been discussed at several Apollo 206 Mission Operations Plan meetings and there was a strong possibility it would not be installed.

In a memorandum to ASPO Manager Joseph F. Shea, Assistant Director for Flight Operations Christopher C. Kraft, Jr., pointed out that his Directorate had responsibility to ASPO of insuring "that all possible test objectives are accomplished. This is done not only by real-time conduct of the mission, but also through considerable premission planning which integrates the desired profile with the Manned Space Flight Network. The underlying purpose of all these operations activities is the accumulation of data, which for unmanned, nonrecoverable spacecraft such as LEM-1 can only be provided through the use of RE telemetry. The FOD (Flight Operations Directorate) does not believe the Apollo 206A Mission Objectives can be assured of being accomplished without the addition of a data tape recorder and associated playback transmitter. . . ."

Kraft said the tradeoff of weight and cost of a data recorder and dump transmitter versus possible loss of data for primary mission objectives, considering the cost of a Saturn IB launch vehicle, a fully functional LEM spacecraft, and the ground support required, seemed inequitable. He recommended that a data tape recorder and associated playback transmitter be installed on LEM-1 (and 2) to ensure that test objectives were achieved.
