Had a squadmate do a test yesterday regarding trees. He was able to fly his P51 right through the trees at 400+ mph, then slow down and land, driving through the trees like they didn't exist.
All the whining by the gv drivers and now we've got some silly concession to appease them. Here's an idea: Don't drive your tank into a tree, rock, sheep, UFO, ANYTHING! Watch where you drive, and avoid the obstacles. It's not hard.
