Perhaps you are not aware that only 2 or 3 years earlier Japan had been
sending over balloons to bomb the west coast of the US. Planes based on
the Aleutians intercepted many but several landed and 6 people were
killed by one. They were armed with explosives and fire bombs intended
to set fire to the forests.

"""On 10 March 1945, one of the last paper balloons had descended in
the vicinity of the Manhattan Project's production site at Hanford,
Washington. The balloon landed on a power line that fed electricity to
the building containing the reactor producing plutonium for the
Nagasaki bomb, and shut the reactor down."""

In 1947 americans were particularly paranoic (has it changed?) about
the USSR. In particular the Russians were known to be working on an
Atomic bomb (tested in 1949). Anything crashing, especially a balloon
would have brought hordes of invetigators.

And it is also possible that it was Aliens. 

Mexicans, maybe.
