PHOENIX — The Phoenix Fire Department answered questions Tuesday after video showing the morning rescue of an injured hiker spread across social media.

Our Cliff Castle Chopper recorded as firefighters loaded a 74-year-old woman into a basket in preparation for flying her off Piestwa Peak.

"We do mountain rescues all of the time, but this particular one gathered quite a bit of attention because during the rescue, she was packaged on a hoist in a Stokes basket and she started to spin," Assistant Fire Chief Shelly Jamison said.

The basket and woman first swayed before starting to rotate. The rate of rotation accelerated as the crew on the helicopter brought the basket closer to the rotors.

"Sometimes when we bring the helicopter up from the ground, [the basket] will start to spin," said Paul Apolinar, chief pilot of the police department's aviation unit. "We have a line attached to the basket that's supposed to prevent that. Today it didn't."

Complicating the crew's efforts to stop the spin was the fact that the line intended to stop the basket from rotating broke at one point.

"They tried to stop some of the spin with the line that Paul was referring to, but that didn't work and it eventually broke," said Derek Geisel, who was piloting the helicopter during the rescue.

ABC15 spoke with a former pilot and professor at Embry Riddle Aeronautical University in Prescott who weighed in on the lines breaking. "I personally have not heard of one of those breaking and that would be of concern that they may want to double that tagline or make improvements to it in the future," said Jerry Kidrick.

The spinning continued for about 40 seconds as the crew tried several times to raise and lower the basket.

"When they start to lower the load, [the basket] does actually start to stop," Geisel said. "And then we slowly brought it back up, it gets into the same downwash from the aircraft and it started to spin again."

"Once we got the forward flight, the spin got to the point where they were safely able to bring the patient up to the aircraft," Geisel said.

About a minute after the spinning began, it subsided and the basket was brought alongside the crew area of the helicopter, which landed at an ambulance.

"[The potential for the basket to spin] is something that's a known phenomenon in the hoist rescue industry," Apolinar, the chief pilot, said. "In the last six years, we've used a hoist 210 times on mountain rescues. In that time, we know of [a similar situation] happening twice."

When the helicopter crews train for the basket to spin, Apolinar said it happens so infrequently that they must induce the basket to start spinning.

"It's not something that's inherent to the basket or inherent to the bag," he said. "It's just something that occurs every now and then and we train to deal with it."
