There was only one plane allowed to take off after flights were grounded on September 11, 2001. It was a plane carrying antivenin to a man bitten by a highly venomous snake.

The grey wolf has been the notorious villain of fables and fairy stories for centuries, yet this highly intelligent and sociable animal has done little to warrant its terrifying reputation.

Wolves are highly territorial animals, and generally establish territories far larger than they require to survive; in order to assure a steady supply of prey. Territory size depends largely on the amount of prey available: in areas with an abundance of prey, the territories of resident wolf packs are smaller.

Lions communicate through a range of behaviours and their expressive movements are very highly developed. They will perform peaceful tactile actions such as licking each other and rubbing heads. Head rubbing, or nuzzling, is a common greeting behaviour for lions. They also communicate through a variety of vocalisations including purrs, snarls, miaws and hissing. Their vocalisations also vary in intensity and pitch.
