OP here. This was recorded on the camera system I helped design and build. It shows the ionized atmosphere during a Mach25 reentry from low earth orbit. I'm still blown away by how well it worked. There is a protective window that shields the sensor from the 10,000°C conditions just an inch away. Landing happened at Koonibba Test Range in South Australia
Nice job, with a really cool result. Looks like that craft almost went beyond the infinite.
