I also participated and must say it was one of most memorable events that comes to mind in my several years of flying in BVA (the other event was probably the Colorado VFR challenge). The real kicker was stacking up to land, with the final approach procedure all based on flying a specific bearing past an NDB at a specific airspeed and using a stopwatch. Even ATC did not rely on the usual radar, using position reports and a stopwatch to go by, and Kunming approach did a great job juggling everyone's position in the queue. I came away with huge respect for those who actually put their lives on the line with these flights and the operators who supported them. There was obviously a lot of time and thought that went into planning for that event, including the route, navigation, historical background, ATC procedures, and scenery design. A big THANKS to everyone who helped make that happen and like Bill, I'm hoping our new BVA venue will provide us with an opportunity for more events like this and a wider audience.
