these guys have the noise canceling headsets but it doesn't block it all out and it will drive you crazy. >> it will. for a lot of these people, it is the sweetest noise. when you hear this above you and you are desperate and you need a way to get out of the water, it's allowed. i will give you that it's annoying. we apologize to the audience. it's loud but it's the sweetest sound a lot of these people today have ever heard in their lives when they get on board this black hawk helicopter. it's taking them someplace where at least they know there is a tomorrow. when you are on your roof and you see the water rising, it's unclear. the silence and that point in time doesn't do you any good at all. the rumbling of the helicopter, that does you good and it warms your heart. yeah, and it's loud.
