MOR et al...
The AAIB have reiterated, in a report
today, the "responsibility", whether or not you can see your wingtips:
Like the towing crew, it might be expected that ATC should have predicted the collision and provided forewarning to the crew towing G-BNLK. However, the vantage point provided to the ground controller only enables the identification of obvious potential collisions and therefore the onus for obstacle clearance must rest with the person responsible for the aircraft, be it the towing crew or flight crew. This is borne out by the instructions in CAP 493 Manual of Air Traffic Services in which an ATC service is provided to assist in preventing collision between aircraft on the manoeuvring area.
