The Antonov AN-12. On this plane, you can manipulate the engine thrust to take off or land at your own pace. You can even slow the plane right down by bringing the slider on the left of your screen downwards with your mouse. Of course, you need to press 1 to use the slider bar on the left. It is recommended that when you first spawn the plane within the sandbox world, that you IMMEDIATELY press 1 and push the slider upwards, to the very top, with your mouse. If you don't do that, then the plane will automatically take off, without your control input, as the engines are always powered on and cannot be shut down - the major disadvantage of having the ability to use manual thrust. Also, when you are on the ground, I recommend holding LCTRL to keep the plane stationary.
