Yep, one of my most exciting landings in the RTW race was at an unlighted strip in South America. At night. In a thunderstorm. I was flying dcc's P-38. There was zero (0.0) chance of finding that airport were it not for some of our team mates on the ground. 10,000 foot lighted runways are not always available. It's good practice to pick the hard ones, during practice...
