First, thank you for your service. Had a few family members in USAF and although people make it sound like a cakewalk, I know it’s not. I recently had the honor of meeting one of — if not THE — greatest pilots. He volunteered to fly the Jews from Yemen to Israel. Great man. Takes something really special in a person to risk his life for other people.
Unlike religions, we Jews don’t believe we’re the only ones receiving divine reward.
R. Singer is a tzaddik. The menschkeit this man possesses is unparalleled. All day long, he gets the same basic questions asked by people trying to trip him up, and he always manages to quickly find some tidbit to make every answer unique to the person asking the question.
One who practices intense emunah can do what he does where he does it. HaShem protects him so well for the mitzvot he routinely does.
We have a saying that might apply to your question: falsehood has no legs.
