Sorry - DE - I don't buy it. The magnetic flux at 40 miles is not that much greater than at ground level.
Basic geophysics.

Oh - I WAS WRONG - It is actually LESS at 40 miles altitude than it is at ground level.

re: "THEN - How the hell did the Enola Gay manage to keep flying after dropping the A-Bomb ? "

The same way that old cars would probably continue to work following a distant EMP attack. Fine circuitry is what's most vulnerable to shorting out, not the clunky wiring that you'd find in a Model T or B-17. They might be vulnerable to a huge EMP, but probably not to a small one.

In response to the question "Did the Hiroshima bomb create an EMP?" Quora says:

Localized - meaning within a few tens of kilometers. All nuclear detonations create electromagnetic energy which overwhelms radios, microwave, etc…. unless they are detonated at an altitude which is high enough to interact more with the earth’s magnetic field rather than atmosphere, then EMP from a single detonation is not a widespread phenomenon. To create widespread EMP damage to ground based infrastructure, you need to detonate at an appropriate altitude with a certain level of yield. Theory says three 1–4 megaton devices detonated 40+ kilometers above the US will paralyze communications, destroy microprocessors and possible burn up large portions of the electrical and wireline telecommunications infrastructure.
