Akrotiri mid '60's . Javelin overhead ready to join circuit when canopy disintegrates. With debris flying everywhere, pilot says to nav. 'if we have to, can you eject?' Nav only hears key word 'eject' and bangs out. As he floats gently down into Episkopi bay he sees the a/c make a perfect touchdown. He was picked up very quickly by a chopper. BoI recommends the word 'eject' is only to be used as a command.
