colourlessponyWhat happens to flies when you let them fly out the window of a car at 75 mph?
T3CHT So birds can get their wings broken by sudden gusts while aloft. Without accounting for size (reynolds number) and reaction speed - a fly would suffer a similar fate.
But I’ve seen videos of insects and/or flies hit with directed blasts of air. They react very, very quickly by adjusting orientation and shape. If a fly tucks fast enough it might survive the aerodynamic forces due to its reaction speed, and be left to the fate of where it’s path goes while it slows to a flyable speed.
And size matters. What seems to us a thin and uniform body of air gas for them is thicker and rippling with waves of density and speed. The wrong placement might kill them with pure shear or high pressure, but I suspect they have the ability to surf those waves as well, and maybe even use them to steer through extreme conditions.
ScubusThe acceleration over time(g force) is determined by the balance between the size and shape of the wing compared to the momentum of the flies body, as long as that proportion is extremely small it would fall below the material strength of the wings connective tissue. Seeing as their wings are extremely small and their momentum is extremely small, the only real variable here is the shape of their wings(technically im referring to its aerodynamic drag versus lift both with respect to the vector of motion, but were just gonna say shape{also when i say “wing” im referring to the area exposed to oncoming atmosphere, which would include the body}). As long as the shape isnt too big in comparison to the momentum, it should be fine.
Tl;dr/eli5: if it tucks its wings it will survive. At that speed if it untucks its wings they get ripped off and the fly becomes a walk.
