In our first series, we learnt about the history of vertical flight and discovered the key pioneers and revolutionary moments that created the rotorcraft industry we know today.  In our second series, we learn more about the helicopter’s role in society, and how it helps overcome obstacles, protect the public and ultimately save lives.  In this episode, we hear how at the end of the Vietnam War, thousands of young helicopter pilots returned to the US looking for work.  Many of these men used their flying skills to adapt the helicopter for new jobs, along the way creating entirely new industries that still play a critical role in society today.  Airborne law enforcement is one of the most important examples.
