They wouldn't need tanks. All they have to do is open the external air vents a bit more but that costs money. The ****pit gets lots of nice fresh air, but then again, we do want the pilots to stay awake.
I used to be a management consultant and did some work at Schiphol airport in Amsterdam. One of the maintenance technicians told me that it takes a very strong stomach to change the cabin air filters. The filters were always covered in a blue-green blob of sh-t that looked like it came out of a horror film. But the worst was the smell. Something to keep in mind next time you fly.
Enjoy your dinner!
