More detailed reviews within NASA showed there were still no obvious insurmountable problems that might block the plan. However North American was not too receptive to the idea.

Kleinknecht was studying the differences between spacecraft 103 and 106, where the high-gain antenna might be a problem. It seemed possible to use LM-2 to support the flight, but Joseph Kotanchik, MSC, suggested flying a simple crossbeam instead of a LM in the event the pogo oscillation problem remained and pointed out that even if pogo was solved the LM would not be needed. Low called Richard and Hage, who agreed with Kotanchik but still wanted mass representation to avoid possible dynamic problems. Low then called William Bergen, of North American, who was not too receptive to the plan.
