The Air Force research crew on the WC-130J Super Hercules airplane was cruising at 28,000 feet over the Pacific Ocean, preparing to deploy 25 weather-sensing devices over a long band of water vapor known as an “atmospheric river” when the hazards of air travel got in the way of science.

Lt. Col. Jeff Ragusa, a pilot with the Air Force Reserve 53rd Weather Reconnaissance Squadron, known as the Hurricane Hunters, was on the second of 12 missions to study atmospheric river storms and was ready to drop the sensors when fuel suddenly began leaking from a tank, forcing the aircraft to turn back.
