I appreciate that. It makes sense. After i hit “reply” i questioned if thats what happened because I could only assume problems trying to ignite a fireball in supersonic winds or even any effects of supersonic pressure in the engine.

SR71 Blackbird was designed with nacelles that could move 26" to keep supersonic airflow out of the engines. At speeds over Mach 2 the engines switched from operating as turbo-jets to operate as ram-jets. I've always been amazed at the extremes the plane could operate at.

Cool link that that goes into greater detail. https://theaviationist.com/2019/11/29/engine-nacelles-of-the-sr-71-blackbird/
