If the monthly ASR publication is anything to go by, FZ are reasonably well practiced at missed approaches, with several each month. As there are no corresponding ASRs to say that the engine fell off, logically these can be assumed to have been completed with both engines operating. Until now, no one had managed to crash, unless of course these are all the work of one insanely gifted pilot, or the FDM failed to register the corresponding aerobatics that we are led to believe accompany this difficult manoeuvre.
