what happened after the discovery was made. >> tyrone benton may well have seen the first signs that something was very, very wrong on the deepwater horizon. >> did you ever get close enough to the leak to see what exactly was leaking? >> yes. we flew down to the pod and saw that there was an angular fitting that had a leak on it. what was connected to the angular fitting, wasn't anal to see. but an angular fitting did have a leak. >> the mechanisms that control the blow-out preventer. if they don't work, the blow-out preventer doesn't work. a leak, even if only a trickle, is a warning. >> yeah. abnormal. >> abnormal enough that you reported it to your company, to transocean, to bp? >> that's correct. >> one pod is always working.
