Joel Boyers and his fiancée，Melody Among，were heading home from the Nashville airport after she earned her helicopter's pilot license when Boyers received a call from a stranger.The caller told him that her brother and his two daughters were surrounded by rising floodwaters in Waverly，60 miles from Nashville and they didn't think they would survive.
   Desperate，the caller had Googled "Nashville helicopters"，and Boyers's company，Helistar Aviation，was the first to pop up.She asked， "Could you please，please rescue my loved ones？"
   Boyers，41，looked west toward Waverly and saw the storm clouds. "Ma'am，" he said， "no one will fly in this weather." But even before he finished the sentence，Boyers knew they would go back up.He put the brother's address into his phone，then he and Among，30，drove back to the airport.Soon，they were in the air，unprepared for what they were about to see in Waverly.
   The flooding took out cell phone service，meaning Boyers couldn't use his phone to pinpoint the house he was looking for.He flew on anyway.Maybe he'd get lucky.
   As Boyers flew the helicopter，Among began searching for people stranded on roofs and bridges.One rescued man pointed to a teenager who was barely out of the water，soaking wet and exhausted，one hand grabbing a tree branch，the other a dog she'd rescued earlier.Since there was no place for Boyers to land，he lowered the helicopter until it was just above the water line.The rescued man leaped out and waded to the tree，where he helped the teen and dog onboard.
   Boyers and Among's mission ended 90 minutes after it began，when professional rescue helicopters showed up.It was good timing - Boyers and Among were almost out of fuel after rescuing 17 people.As for the woman who originally contacted Boyers，she called back to say that her brother and his daughters had also been saved.
