And they take off so slow and into the wind that...well...one thing you DON'T want to do is hit one of those big birds on a running cycle!
I have a friend who used to work at Homestead AFB as a structural mechanic and he gave me a few examples of the damage they can do to aircraft. Judging from what they can do to titanium I have no problem believing they could ruin your day even if they just winged you. 
They are among the most disgusting creatures on the planet, in the summer when they get overheated, they crap on their own feet and force blood out of their heads to help cool them down
They don't even like themselves.
I would love to explore the everglades some day except the alligators scare me.
I want to do this too and I hate those alligators too but that won't stop me!lol!
As many gator's and people there are out there attacks are extremely rare. You're far more likely to get in a car accident on your way there than be injured by an alligator.
