Incredible footage released to the internet today shows a the POV of a Russian pilot as he ejects from an Su-25SM3. As far as I know, this is the first and only footage like this that exists.

We will update this post when more context becomes available, but this is allegedly the POV of a Russian pilot wearing some sort of action camera as his plane is shot down. The footage shows the full ejection process including the pilot impacting with the Earth and looking around in a dazed state.
