The most salient part of the report....
At their closest point the aircraft were 807 metres apart; however the rate of closure was low. At this point, EI-EFF was past the intersection at TWY E5 accelerating past a speed of 138 kts, EI-DHA was approaching TWY E3 at 146 kts and decelerating (Graphic No. 1).
Now who hasn't 'been there, done that'...
Maybe the multiple 'garbled transmissions' needs investigating though.
