Nav Survived; Tornado F3 In North Sea
There was also the case of the F3 that crashed into the sea whilst 'bugging-out' of a merge (c1988). It hit the sea and the Nav survived but with no recollection of having pulled the handle.
Remember that irrespective of what the command eject is set to (BOTH or REAR), the back-seater ALWAYS leaves first, irrespective of who pulls the handle.
