Dad worked in the Air Force in the 1950’s and told me of an event he attended (VIP event) where a nuke test was done. He said it was an airdrop.
The USAF did drop bombs from planes over the Bikini Atoll in the 50’s-60’s.
They then flew planes threw the mushroom cloud after it had cooled to measure the radiation effects.
I knew a pilot that did that. He passed from cancer in 1995? maybe.
That could be entirely true but mostly the air drops were from towers and very limited in scope.
The big tests were all underground.
The first test was tower and understood to never be the kt it was ever again.
No Aircraft drop detonations in the US that I know of.
Is there a reason you are curious about it now?
I have worked various ranges and areas that can shed some light in Nevada but cannot help with NM.
a black tie affair? did waiters circulate with trays of refreshments?
