kim is very concerned about sam. he has a medical condition, and she fears the trauma of the accident may affect his heart. >> sam looked extremely red with the pressure, you know. that was my concern, making sure he remained calm. >> but kim knows if they have it bad, contractor bruce boyles has it worse. he's hanging below them from his safety harness, which is still connecting him to the bucket. one wrong move could send them all crashing into the water below. >> we were just encouraging him to hang on, hang in there, help was on the way. >> kim doesn't know it from her position in the bucket, but the contractor who fell into the river has survived and is pulled to safety below. now rescuers on the bridge are trying to devise a plan to save the rest of them. >> captain randy fulford was one of the individuals that i knew had recent high angle rescue training that i knew would make the rescue more safe, both for the individuals we were rescuing, but also for our own rescuers.
