From the “You Were There” book on NASA I should write. Back in the 1970s the US had a stockpile of nuclear bombs which could be dropped at fairly low speeds. The think tank in DC wondered if they could be modified to enable them to be dropped from the current aircraft which were capable of much higher speeds. Like nearly supersonic.
So we did a proof of concept test. The designers took the existing bombs and modified them in a variety of ways - long tail extensions, pointy noses, different fin configurations, etc. Scale models were built. The miniature bombs were attached to an F-16 scale model and installed in the 8x6 transonic wind tunnel.
Data taking was simple. We mounted a Nikon camera looking through a viewing port. It had a spinning disc in front with a dozen radial slits to act as the shutter. The camera was set for say, a 1/100 second exposure while the disc spun at a specific rpm. The result was an 8x10 photo with the bomb caught in a dozen stop-action positions.
The first results were catastrophic. The bomb fell a few feet, flipped end over end and struck the tail! But they finally figured it out. They designed a blunt nose, high drag configuration. When done the bomb fell cleanly away and quickly adopted a nose down condition.
I have no idea if it was every adopted.
