On the 10 Air Tanker DC10F, there is a tank below the plane. In the SYSTEMS tab, there is an option to OPEN TANK which is only available in the air. What is that tank supposed to drop and why does it have to be there?
It’s support to carry water or retardant for fires, the tank opens at the bottom while flying it’s just a cool feature
Also useful for water parks!
That was funny lol hopefully my answer, answered your question!
