.... You’ve sent me down the A-12 Rabbit Hole.
Pictured: D-21 test assembly on the same in Burbank Skunk Works.
I love this photo because the tools (oxy-acetylene torch! Harbor Freight-ish hand crane. Plywood security screen! ) seem so ordinary. And what they were building was so extraordinary....

It looks like a proper gantry crane to me. Buy yeah, Skunkwo rks is awesome.

I just meant that it was pretty ordinary stuff... not exotic, not high tech.

That’s an interesting photo too, early in the program. They stopped using the aerodynamic cover on the intake because it wasn't really needed after all, and it tended to damage the M-12 and D-21 when it was ejected.

What you said made me realize something about aerospace/airplane/I don’t know the technical term for it development.
Relative to what I know about the technology and production processes involved in producing cars in the 40s-60s it’s astounding what we were doing with planes and space exploration. Things that today still present immense challenges for engineering and science we being conquered back then. Amazing

Yeah, this.
And, we even managed to solve ‘em with no digital computers, no logic analyzers... no transistors even.
One subtle but key “problem” was in the HE triggering of the Fat Man in 1945 (75th Anniversary this weekend, amazingly), which took astonishingly PRECISE simultaneous triggering around the periphery. Sub-nanosecond timing. No MOSfets, no BJTs, no silicon, no germanium. Lim ited bandwidth scopes, limited switching devices.... .and it’s really, really important that it all works right. After being submerged to 70 below zero in the un-pressurized bomb bay of a B-29. At 30,000 feet. At sea level. In unknown weather and moisture conditions. And, only on command.
I’m trained in the field and have no idea how I’d have done that with the tools of 1944 America.
