In the weeks after Hurricane Katrina in 2005, hundreds of lost or abandoned pets from the Gulf region have been evacuated and flown to animal shelters around the U.S. where they can be cared for until they are reunited with their previous owners or adopted by new ones.

The picture displayed here, taken by photographer Carolyn Cole, captures one such evacuation in progess, although it shows dogs being transported by bus rather than airplane.
The image was published by the Los Angeles Times on 1 September 2005, with a caption describing it thusly: "Over 150 dogs and other animals were evacuated from an animal hospital after their owners had left town without them."
The 2 dogs in the front look sad. I hope they have been reunited with their owners.
