Until now, nobody has ever become burnt out with working for the FIRM/Company. In this episode, St. John actually contemplates no longer working for The Company and leaving the Airwolf team.

If you notice when they show the Tanker for the first time, you will see a Canadian Flag on the Conning Tower/Smokestack.
