Responding to a February letter from North American CSM Program Manager Dale D. Myers - suggesting further slips in delivery of 2TV-1 and spacecraft 101, 103, and 104 - Low reminded Myers that at the close of the Configuration Control Board meeting on February 23 he had cited a mid-April target for delivery of CSM 101. Since that time, Low said, KSC had been actively preparing for an early summer launch based on that mid-April delivery, and circumstances therefore made that date most important. Moreover, North American must deliver CSM 103 by the end of June 1968 in order to ensure meeting Apollo's end-of-the-decade goal. He reminded Myers that he had pursued this point on several occasions with him and with William Bergen. They both had told Low that they had found ways to deliver 103 within that time frame, and Low now suggested that this target date be made a firm commitment in the official Apollo schedules. At the earliest possible date, Low concluded, MSC and North American must establish firm contractual baselines for delivery schedules. Until then present delivery dates remained valid. He admitted that some schedule slips had resulted from NASA-dictated changes and that the schedules should be adjusted accordingly. The remaining delays, however, Low attributed directly to the company's inability to meet projected commitments. The contract was changed to call for an April 1968 delivery for CSM 101 and a June 1968 delivery for CSM 103.
