I thought all dnata pushbacks at Dubai were done by a engineer on headset and a rampie driving. At least it used to be. The head engineer who used to sign off handlers to do pushes was very strict when it came to training and signing off ramp crew to push aircraft.
P.S i do know ramp staff who have reported fuel leaks and damage to aircraft prior to pushing. Before anyone goes at me i see the argument for engineers on the headset.
