I've just been reading the report posted by Dave Reid. Something I wasn't previously aware of - maybe I missed it here - is that the missile battery operators had set up the orientation incorrectly:
- One of these mobile air defence units was located in some proximity to IKA airport, where its operator failed to align it properly, making an enormous directional error of 107 degrees off north;
- ........
- The operator mistook a 40-metre long commercial passenger jet taking off and ascending from east to west for some sort of threatening aircraft or missile coming in from west to east;
