Air Transport Units (White Giant)

All of my air transport units are out of aircraft fuel and do not move for this reason. I have lots of supply units. Why don't the supply units resupply the air transport units? Is there anything someone can tell me to help me resupply these transport units? Any help would be appreciated.

I had the same problem with my air transport unit. I have more than 20 supply units. My air transport unit was out of fuel for a long time. I tried having it refuelled. Clicked on a couple things with no results. I recently, dismantled it. Yes, any advice would be greatly appreciated. Thanks, Dave33. New Lethal
