had the other fireman's hand. he said, come on, big boy, we're going to get you down. as i grasped his hand, i felt safer. i knew that he wouldn't have let go of me no matter what. >> if anything, the ordeal has strengthened their commitment to firefighting and to each other. >> i trust these guys with my life every day. i knew they were going do whatever it took to get me. if it took another one going down also, i knew they would do that. because we do that for each other. it's a brotherhood. coming up, a boat stuck in the ice in the bering sea. >> when we heard them say survival suits on, that keyed us to say this is not a salvage anymore, boys, we better be ready for a rescue. >> when "caught on camera: extreme rescues" continues. i'm billy, and i quit smoking with chantix. i decided to take chantix to shut everybody else up about me quitting smoking. i was going to give it a try, but i didn't think it was going to really happen. after one week of chantix, i knew i could quit. along with support, chantix (varenicline) is proven to help people quit smoking. chantix definitely helped reduce my urge to smoke. some people had changes in behavior, thinking or mood, hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. some had seizures while taking chantix. if you have any of these, stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse or of seizures. don't take chantix if you've had a serious allergic or skin reaction to it. if you have these, stop chantix and call your doctor right away as some can be life-threatening.
