How did they do this video?

BUT at about that time vidicons were becoming popular too. The TK42 used three 1 inch vidicons in the RGB channels. The 1 inch tubes were not quite as sensitive but they probably worked well outdoors. The TK27 film camera used a 1 1/2 inch vidicon in the luminance channel.
I believe I still have some old 1 inch tubes.

Both ABC and CBS had custom hand-held I/O cameras. I've seen ABC's used at ringside on boxing coverage. There's photos of the CBS camera shooting inside a Mercury Capsule mock up at McDonnell-Douglas in St. Louis during space shots.
Scenes were shot with anI/O, not a vidicon. You can see the familiar black halos around the fireworks and other extreme highlights.
The technology to microwave the video back short distances certainly existed then. I'd love to see the equipment and manpower standing behind the camera.
