NASA's B-57s originally had FY1953 serials (as B-57B/RB-57D), so a few years newer than the M-B Meteors.
They were given FY1963 serials when converted to RB-57F standard (later redesignated WB-57F) for NASA, and the TF33 (JT3D) engines that they now fly with are probably around 10 years newer than the Meteors' Derwents.

Pretty much the same age as many of the USAF KC-135's still in service, and the active B-52's are all 1960-1962, so not much younger.

This Hunter probably has a Martin Baker Mk 4 seat in it (although some single seaters had earlier seats), and this seat has a 80 ft/sec gun which is at the limit for damaging your back (rocket seats have 60 ft/sec guns). When you bang out there is a probability that your spine will not be straight as it s difficult to be sure that you are sitting correctly. If your spine is straight all the vertebra will be parallel and you should escape any injury. However, if your back is slightly bent then the vertebra are likely to collide with each other and fracture - depending on the bend this will be the front or the back of the vertebra bones that will fracture, and in the day you might expect several weeks flat on your back to allow the vertebra to re knit..

The ejection from the Hunter though ended his fast jet flying days as a TP with BAe.

All single-seat Hunters were fitted with Mk2 or Mk3 seats, rated at 90kts/ground level. The 2-seaters all had the Mk4 seat, with the same ejection envelope. One major difference is the Mk4 uses a combined harness, where on the earlier seats there were separate harnesses for the parachute and the seat. Yes, all had the 80ft/sec cartridge gun, which is pretty much on the limit of what the human frame will tolerate, resulting in a spinal injury rate of around 30% for such seats. Not as bad as it sounds, as the vast majority of people have a full recovery and most regain their ejection seat rated medical category. Rocket seats are kinder to the body, not just because the gun has a lower velocity, but mainly because the rate at which the G is applied is significantly lower.

Martin-Baker refitted its Meteors with Mk10 rocket seats rather than keeping the old 'gunpowder' seats, so I'm sure that it would be feasible to refit Hunters similarly. But at a cost...
