It is December 1945, and a squadron of five bombers are conducting a routine flight over the Atlantic Ocean. Yet even though the mission seems to involve minimal risk, somehow the pilots have become disorientated.

And the mystery of their disappearance remains unsolved for 70 years – until scientist Karl Kruszelnicki claims to have the answer.
