At 200 feet, the first pilot, Chris Gullikson, was perfectly visible in his trike’s open cockpit. He was wearing his whooping-crane costume, a white hooded helmet and white gown that looked like a cross between a beekeeping suit and a Ku Klux Klan get-up. Gullikson and the other trike pilots were going to pick up the 14 juvenile whooping cranes that they were, little by little, leading south for the winter. Traditionally, and for many millenniums, cranes learned to migrate by following other cranes. But traditions have changed.
