!!!error: Indecipherable SUB-paragraph formatting!!! on the F-16 start up got me remembering how the J58s on the SR-71 had to be mechanically started by way of a V8 "Start Cart" before pneumatic starting was available.

Below is a video I found that has audio of a start up with a few pictures and some explanation.

Even better than starting the engines !!!error: Indecipherable SUB-paragraph formatting!!! , in my opinion.

I think the engine in the audio is the nail head.

Sounds like BBC to me

I think you're right. Doesn't sound like a BBC to me. I saw one of those carts at the Museum of Flight in Seattle, I believe that one was a Buick engine. Pretty cool rig. Plus it was sitting right under an M-21, which I think is the only one on display.

I can confirm the one in Museum of Flight in Seattle is a Buick. We go there all the time when visiting family. Never gets old. I always smile at the juxtaposition of a plane whose pilots can earn astronaut wings being started by a Buick V8.

I still don't understand how these carts work, did they turn a fan that spun the compressor?

The V8s had transmissions that drove a vertical shaft that connected to starter mechanism on the J58. Essentially, they directly spun the J58 up to speed.

Makes sense, It didn't look/sound like a fan system.
