Also, the US would take worn out B-24s, fit them with remote control flying equipment, fill them with explosives, and have a crew of two pilots fly them near the target, engage the r/c from a shadowing aircraft, and bail out.
The flying bomb would then be flown into a hardened target.
“engage the r/c from a shadowing aircraft, and bail out.”
Unless it blew up first. Which is why JFK was president instead of his brother.
