Reality check:

The top of Mount Everest is about 5.3 miles above sea level.

WWI Zeppelins could reach about 3.4 miles above sea level (and WWI
aircraft flew higher still).

WWII aircraft could fly at least 6 miles above sea level.

Modern SAMs (Hawk-style, not man-carried) can reach at least 10 miles
up, indicating that modern aircraft can fly higher still... and they
still don't move anywhere close to the outer reaches of the atmosphere.

Roger, I'm afraid your estimate of the atmosphere's thickness might be
a bit low :-/
