Well, according to HrnFixr (henceforth to be referred to as "SuBrkr"), if you hit the "D" button at any speed in SF/FF/WoV/WoE/FE, you'll hear a warning tone that sounds like "Durdurdur", and whichever aerial conveyance you may be in, will perform a maneuver called the "Hissing Viper". Immediately upon hearing this, I fired up Google, looked up "Hissing Viper", and read the following:
Habitat and Habits: A snake of open, sandy woodlands - found in the wooded dunes of western Michigan. The upturned snout is used to burrow after toads, a favorite food. When threatened, hognose snakes puff up with air, flatten their necks and bodies, and hiss loudly. (This has led to local names like "puff adder" or "hissing viper.") If this act is unsuccessful, they will writhe about, excrete a foul smelling musk, and then turn over with mouth agape and lie still, as though dead. Despite this intimidating behavior, Hog-nosed snakes are harmless to humans.
Now, knowing that USAFMTL is a native of Michigan (and that the aforementioned Hrntfxr is always setting him up), I smelled a rat....or was it just the airframe excreting a foul smelling musk as it rolled over, intake agape, and lay still?
