The whole thing is nonsense. If we has made alien contact in 1947 we never would have fought the cold war as we did with utmost seriousness. Evidence can be faked, but human nature cannot. Apart from that, Harry Truman was a blabbermouth, and the idea he could have kept such a secret until his death 25 years later is not at all plausible.

SPACE ALIEN DISGUISED AS JAY LENO SEDUCED ME!
A Love Betrayed!
A pretty supermarket cashier was left emotionally devastated by a close encounter of the heartbreaking kind: She was seduced and abandoned by a smooth-talking alien who looked just like late-night TV comic Jay Leno!
"I knew he wasn't the real thing, the moment he kissed me," says Claudia Sandersky, 25, of Los Angeles. "Jay's happily married. And when this creep just dumped me in the street and drove off, all my suspicions were confirmed -- Jay could never treat a girl like that.
I doubt "they" (lol) would have told Truman anyway if he was a blabbermouth. Actually they probably wouldn't have told him even if he wasn't.
I think that the theory generally is that the occupants of the craft did not survive the crash. Consequently, there wasn't anyone to make contact with - merely some corpses and a lot of debris to analyze.
Apart from that, Harry Truman was a blabbermouth, and the idea he could have kept such a secret until his death 25 years later is not at all plausible.
The secret wasn't kept, at least initially: the Air Force announced that a crashed flying saucer had been recovered.
Welllllllllllllll, that makes clear how much solid research on the topic you have
NOT
done!
And, evidently you also do not have a close relative who worked around such craft daily in Nevada.
Some of us no longer have the luxury of not believing.
I'm not persuaded we made alien contact in 1947--I'm not convinced the evidence from Roswell is sufficient to conclude that. However, the government was certainly interested in widespread reports of unidentified aircraft at that time--not just at Roswell but all over the country and even abroad--and these reports were actually viewed in the context of the Cold War by the military and the intelligence agencies. There was concern that the Soviets might have gotten an edge in extrapolations from German wartime aircraft/rocket advances (there had also been UFOs of various types spotted during the war, notably the foo fighters), which was particularly alarming because there was a high concentration of UFO sightings around US nuclear research facilities, plus the Japanese were known to have attempted to use balloon bombs as bioweapons during the war (fortunately they didn't work). There was also concern over the Soviets exploiting UFO panic for propaganda purposes, as some of the leaders of the citizens' UFO groups had Communist associations (as some still do IMO--I'm quite suspicious of the the Disclosure Project because it seems to have an anti-SDI agenda and to be oriented towards getting into files on classified US/UK military research). There is some interesting discussion of the FBI's investigation of early UFO sightings in:
Bruce Maccabee, UFO/FBI Connection
As a sort of "barf alert" note, I'll that Maccabee's political perspective seems to be a bit different than mine and I'm interpreting some of the documents he discusses differently than he does. Nonetheless, the documents he discusses are quite interesting, particularly if you're familiar with some of the military and scientific figures he mentions. Some of the scientists assigned to investigate UFOs were also prominent in atomic research, and a few of them also come up in discussions of Soviet espionage at that time.
