I watched that whole incident unfold as I was based at Luqa at the time - we knew something was amiss whilst the aircraft was on final. I know who you are talking about. He and the captain were hospitalised after their ejections. Shortly after being discharged the co-pilot was seen strutting aroud wearing his Martin Baker tie. It didn't go down well.
The rear crew couldn't get out of the aircraft as the nosewheel assembly had buckled and jammed the escape hatch. To be fair, the pilots ejected at the same time the fuel tank exploded and the starboard wing detached.
