I don't really know, but I'll have a go at it and see what sort of discussion is generated. I'd have thought that Military pilots are trained to use the ejection seat and that this training not only includes the "how", but also the "when", the "where" and the "why".
Military aircraft are pretty expensive bits of kit, so it's easy for me to believe that the training in ejection seat usage would be very thorough. I'm not aware of any civil syllabus to equal it.
Ahhh... I can se it now :- Civil Pilot Bloggs gets into some difficulty over the top of downtown London (or insert any other major city of your choice). He "bangs out" and all goes exactly as advertised and he lands safely clear of the aircraft, with perhaps only some minor back pain from the force of the ejection. Meanwhile, his now pilotless aeroplane has chosen its own point of impact ... somewhere in the middle of the commercial district.
Remember too that the force of the ejection can be considerable and that the Military blokes/blokesses have all sorts of protective clobber to wear, to help minimise bodily damage. I could probably say a fair bit more, but that should be enough to prove my ignorance of the subject and allow more informed comments to appear.
