IMPLICATIONS OF THE FAILURE
From available evidence the cause of failure cannotetermined. If no major redesign ofehicle isa launch could probably take place fromefore the end easonable manned lunar landing program schedule would not require the first dual launch j. until the spring ofallowing sufficient to repair. anned lunar landing would not appear possible before2 or, moreanding would, of course, be further delayed if major redesign ofehicle is necessary.Original document.
