Never assume,
A car had lost a wheel or something on the first corner into the drop off zone, cars had to enter via the exit loop near delta and then let some cars out,etc, minibuses had to 2 point turn to enter via the exit loop.
This went on for over half an hour till some head scratching and decision was made to manually lift and shove the car into the drop off zone, i watched its all and got caught up in it whilst leaving from the cta. fire crews arrived but it had been moved by then.
Lots of cars were swapping lanes and asking questions to the airport staff dealing with it.
One consequence of having single lane entry into the drop off zone i suppose.
It was all running smoothly up until then.
