Just remember guys and gals. If you start at 12 and it drops to 9 (with engines running) prior to takeoff on your Bme-Syd-Bme flights and return to the bay in Sydney for more oil, the company could view that as unprotected industrial action. You can protect yourself from such a claim by calling for more oil when you get to Broome. If you make it of course.
This whole scenario is absolute madness.
