Another epic episode of Supreme Skills!. This is the 2nd half of our flight duration competition for bamboo copters. Competing are a super-confident aeronautical engineer who's worked on innovative jet engines, and a maverick professor of biomimetics familiar with shapes and traits that evolved over millennia. But in Part 1, neither specialist was able to make a bamboo copter that flew very long. They must now exercise all their creativity and technical ingenuity. Don't miss this showdown!
