Andrasz :
the airport controller, who could have waived off the aircraft when he saw it was way below glideslope (a firm order to immediately abandon approach would probably have been followed by the crew who all had a military mindset),
I do not know if this would have changed anything and this is accepted in Poland Air force (*) . In many Countries (my own ,and I suspect valid for rest of NATO Countries) a TWR controller cannot order a go around for visibilty reasons. It is always the PIC who has responsibility and decides to break approach, not the controllers. Going below "glideslope" is also not unusually a go-around factor in the military,( especially in airfields where there is no ILS !)
Incidentally this airfield had a PAR but a PAR APP was not requested ( page 116 of report.)
(*) the YAK 40 which landed earlier was apparenttly told by ATC to go around, " but the crew ignored the instruction and landed." (page 114 or report)
