aerodynamics (pictures in flight)

Thought it would be cool to see various pictures of aerodynamic things / creatures in flight.

I would assume a humming bird was extremely slick, but you will have to be damn fast on the camera trigger to capture it with its wings folded in forward flight.

I have actually for a while contemplated if i was able to take a picture of a pellet / slug as it leave the barrel, but i have not yet dusted off my DSLrs for that experiment.
Also not even sure they have a fast enough exposure, generally when i take pictures i am at the other end of the scale in low light.
