About the film
Operation Blue Jay was the code name for the construction of Thule Air Base, which is now known as Pituffik Space Base in Greenland. It started as a secret project, but was made public in September 1952 through Life Magazine. Blue Jay brought 7,000 construction workers to build the secret cold war base.
The project built a three-kilometer long runway to service large B-36 Peacemaker and B-47 Stratojet bombers.
