Sloping Runways
If you really want to see an prime example of a sloping runway, try looking at either WAU or BULOLO - i forget which one but the slope is from memory about 17 degrees. The old DC 3s used to land up slope and turn left onto a level hardstand at the end of the up slope - full throttle required otherwise they would roll back down the strip.
Take off no problem - point the nose down hill and away you go except for a few pine trees at the end of the strip.
I used to have some photos but have lost them in many moves.
