Blue Angels and spray paint

When I am walking on the street, to the grocery store, or even at my home, people come by to lecture me about the environment. I want to say to all of them, "I am not the problem." Why aren't they stopping the Blue Angels?

For a while there, I remember I could not buy a can of spray paint. The thinking was spray paint cans were destroying the ozone, because they used chloroflorocarbons as propellants.

What do the Blue Angels use?
What is their effect on the environment?
