The substitution of the two smaller X-1-type engines was the obvious solution to our dilemma. Actually, the customers had already considered exactly the same idea. They approved it at once, and Edwards got busy building up a dozen “proven” X-1 engines from old parts. We planned to put two each in the first two X-15s, holding the third X-15 in the factory for the first XLR-99 engine and other improvements which flight test would generate. The remaining X-1 engines would be used for ground tests in the X-15 engine test beds at Edwards and RMI.
A few nights after this decision was firmed up, Stormy, Feltz, and I met after work in Charlie’s office at the North American plant. I was still grumbling about “interim measures.” I let off steam.
“As far as I’m concerned, we’ve botched the whole deal,” I growled. “You watch. We’re never going to get that big engine. The X-15 is going to die on the vine. I’ve seen it happen before.”
“You’re wrong there, Scotty,” Feltz said. “We’ll get the big engine sometime. Meanwhile, we’ll get a lot of Mach 3 data which will really help the F-108 and the B-70. We’ll prove out the X-15 systems and by the time the big engine comes the ship itself will be as reliable as an F-100.”
We debated this point for a long while. Stormy was also in favor of substituting the smaller engines. “I want to get this thing in the air as fast as possible,” he said. “I think that as soon as we start flying the X-15 and prove our systems and landing and the rest, Washington will be impressed and may look with more favor on an advanced X-15 or the X-15B.”
That remark was typical of Stormy. He was always looking far down the pike. He had cornered the Air Force combat aircraft market with the F-108 and the B-70, but he was stung when we lost out on the X-15B. He had not given up—and never would.
“Frankly, Scotty,” Charlie Feltz broke in, “this engine thing may be a blessing in disguise. I’ll tell you honestly that all along I’ve been a little concerned about busting into space all at once with a brand-new airplane and a brand-new, untried engine. They did it with the X-1, it’s true, and it was a real good show. But this is a new dimension we’re getting into. They were just trying to crack Mach 1. We’re trying to crack space, with a new pressure suit, re-entry, new metal, landing—everything at once. I’ve got a real good buddy who’s going to be flying that airplane for the first time, and I’d just as soon have him around for a while.”
Put that way, on a personal basis, there was nothing I could say in reply. From that point on, I resigned myself to the engine substitution, even though, in a sense, it marred my dream to help build and then fly the perfect airplane. In fact, after some weeks, I came to believe that even from a pilot’s point of view the engine substitution was wise. We could learn to crawl before we entered the Olympic hundred-yard dash. I was confident that in time and with God’s help we would eventually succeed with the big engine. There was too much at stake to allow it to fall by the wayside.
