Once while on an emergency call to repair an air traffic control tower communication problem at night, I was cleared to take my personal car down the taxiway, the controllers were going nuts and told me to expedite, so my car being an '85 Supra I did, at about 80mph it looked like a gray sheet was pulled over the windshield as thousands of little birds lifted off the taxiway, I'm sure over a hundred of them splattered on my car leaving the grill clogged and entire front a stinky, bloody, feathered mess. Was not a pretty site! It took weeks before the smell went away.
