Apollo’s funds escaped unscathed, however the follow-on Apollo purposes software was once all yet deleted. 2 The LM application at Grumman without delay felt this budgetary belt tightening. Grumman’s charges had risen dramatically, from $135 million in economic 12 months 1964 to $350 million in economic 12 months 1966, attracting the eye of NASA administration. NASA’s first flow opposed to Grumman’s elevated spending healthy good with a wish that have been development in Headquarters to transform the Apollo contractors to incentive contracts from expense plus fastened expense.
