Some of the best times as a engineer was at Riyadh where I had runup and taxi aut on 747.A300-600 and L1011. We were checked out and had ramp checks by other staff. I even had high speed aut on A300 and B747 had them up to 50 kts.
The best part was taxing over the main car route into the airport looking down on the cars coming in. We always had to have all checked out staff in cockpit so we looked after each other.
Keep them flying
