DAR - Eeek - likewise! The only time I would start sweating were those few times when some small issue would require a return to the gate or elsewhere on the ramp, followed eventually by lining up for departure, and still flaps retracted. Of course they'd always wind their way down and we'd be fine but a few times I thought we were going to dot the "I" on the big "South San Francisco..." sign on the side of the mountain. I was sad when Kai Tak closed - only had a few arrivals there but loved them.
