Ten years ago, amateur historian Craig Mitchell discovered the wreckage of a World War II- era warplane lost above the hills of Hong Kong in 1945. After a decade of work, Mitchell put together a team of archaeologists, engineers, experts and adventurers, to mount one of the largest World War II archaeological expeditions in recent Hong Kong history, in a quest to find out what happened to a missing Avenger warplane in the final year of the war.
