Hmmm.

Starfish Prime[edit]

Main article: Starfish Prime

In July 1962, the US carried out the Starfish Prime test, exploding a 1.44 megaton bomb 400 kilometres (250 mi) above the mid-Pacific Ocean. This demonstrated that the effects of a high-altitude nuclear explosion were much larger than had been previously calculated. Starfish Prime made those effects known to the public by causing electrical damage in Hawaii, about 1,445 kilometres (898 mi) away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms and damaging a microwave link.[8]

Taking the pulse of a nuclear weapon

But the effects were far more than a simple light show. When the bomb detonated, those electrons underwent incredible acceleration. When that happens they create a brief but extremely powerful magnetic field. This is called an electromagnetic pulse, or EMP. The strength of the pulse was so huge that it affected the flow of electricity on the Earth hundreds of kilometers away! In Hawaii it blew out hundreds of streetlights, and caused widespread telephone outages. Other effects included electrical surges on airplanes and radio blackouts.

Zim: Both snippets were taken out of the middle of the
articles. Perhaps an atomic bomb based EMP needs to be
taken more seriously.

And then I do NOT want the federal government taking
responsibility for 'fixing' the problem. The fed should
do the research and make recommendations for what should
be done, but the local power companies and the ratepayers
should be responsible for the work. (I do NOT want
yet another multi-Billion dollar pork pie being created
for sleazy thieving politicians to steal from.)

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.
