This thread has just brought back a horrible memory of my first command days on a Dak.
Taxiing at Amsterdam, Highway on the right - down below a steep bank; cars whizzing by. Strong X-wind. Left brake fading, more right engine. Going faster. Both of us standing on the left brake. Swinging right, more right engine...even better view of cars. More engine - more speed. Considered Mayday and taking off on taxiway. Considered throwing some of the bricks that I was sitting on, out and under the left wheel. Ug! Bag brakes.
