There are many more projects/ experiments out there, including high altitude thermonuclear detonations from Johnston Island, Pacific Ocean, in 8/1958 called

HARDTACK.

1st detonation destroyed the ionosphere over a vast area around the test and interrupted HF radio and halted transpacific airflights.

Idea was, if they could disable (their word), the ionosphere as a radio reflector, they could replace it. The military had developed "super" high frequency, SHF, tech for

WEST FORD PROJECT, a controversial experiment perceived as potentially dangerous?, and first called Project Needles. This report said it was an attempt to create jam proof military comms, another says it was for global communications.

LINCOLN EXPERIMENT: distribute 480 million 0.7" lengths of #53AWG Copper wire (0.0007") in scatters, into the ionosphere, to form circular path orbits of bands of dipoles. They said as the dipoles slowed they would fall to the earth and be gone in a few years.

So they destroyed the ionosphere, and launched from Cape Canaveral 480 million Copper needles into the ionosphere on 2/11/1965.

If the sun is local, would this scenario cause the sun, our atmosphere, and us and earth harm? Is this what blew hole(s) and weakened our Ozone, and took out our natural sun protection, and would the copper create any adverse effects for us and the planet?

50 nukes in 1957. So many nukes

For you youngsters, all we had was teletype and hard line comms.
