Interesting history from 30 years ago. C-5 Galaxy vectored by ATC to intercept a NORDO RAF GR5 Harrier fighter over the UK. Galaxy crew completes intercept to a formation position close enough to check the cockpit, and take still photos and video for the investigation. That's a heck of a handful of airplane to be maneuvering in close formation with a small plane. Well done.
Pretty cool.
