Sorry to hear the problem still goes on. I had the same problem on the Herc Fleet some years ago. My solution was to go off the flight deck until they stopped smoking, until two older guys(bullies) lit up King Teds.I stayed off the flight deck for 45 minutes, made them work for a living balancing the fuel etc, though i did have my headset on down the back. Only to be reported to my boss when we arrived back at base! Got a right roasting over it. RHIP. Though I,d like to meet them in a pub now! the contents of my pint may not stay in the glass too long.
I hope you remember this Bill and Al, you made my life a misery.
