Brilliant Humpty; brilliant. My last early morning departure from PVG had a ground controller (operating all ground sectors N to S and W to E, and barely able to manage one of them let alone 6 ) sounding as though he’d consumed all the local taxi drivers’ supply of ketamine. Asking for a radio check every 3 minutes airborne (from memory the time period when they report you for loss of comms ) is also worth the effort.
