MIAMI - A surgeon from a Mayo Clinic in Florida flying across the northern corner of the state to retrieve a heart for transplant and two others were killed Monday when their his helicopter crashed.
The heart could not be used in another transplant because its viability expired, and the patient who had been scheduled to receive it continues to wait for a new organ, Mayo Clinic spokesman Layne Smith said Monday evening.
The helicopter departed the clinic in Jacksonville around 5:45 a.m. but never arrived at the Gainesville hospital, Shands at University of Florida, about 60 miles southwest, said Kathy Barbour, a spokeswoman for Mayo, which is based in Rochester, Minn.
Heart surgeon Dr. Luis Bonilla, procurement technician David Hines and the pilot were killed. The pilot's name was not released.
The helicopter went down about 12 miles northeast of Palatka, said Federal Aviation Administration spokeswoman Kathleen Bergen. The town is about 40 miles east of Gainesville and about 45 miles south of Jacksonville.
Clay County Sheriff's Office dispatcher Myron White confirmed the three dead but had no more information to release about the crash in the remote, forested area away from roads. The National Transportation Safety Board also was investigating.
The National Weather Service in Jacksonville reported that there was light fog with overcast conditions in the area but no rain.
"As we mourn this tragic event, we will remember the selfless and intense dedication they brought to making a difference in the lives of our patients," John Noseworthy, Mayo Clinic president and chief executive officer, said in a statement. "We recognize the commitment transplant teams make every day in helping patients at Mayo Clinic and beyond. Our thoughts and prayers are with the families."
FAA records show the Bell 206 helicopter is operated by SK Jets. The St. Augustine company released a statement Monday evening: "The focus of our efforts at this time is to attend to the needs of our passengers, crew and their families and work with the NTSB and local public safety officials to determine the cause and extent of the accident."
Gary Robb, a Kansas City aviation attorney specializing in helicopter safety, said SK Jets is known as a careful and safe operator in the industry. The small, lightweight craft has low weight and speed capabilities and is primarily used by traffic reporters or police departments, Robb said.
"It's not usually used in donor flights," he said.
"If you're on a mission where time is sensitive, why use an engine that is low performance?" Robb said, adding that the helicopter has a cramped cabin.
An NTSB investigator will scour the crash site for clues and look into the pilot's experience and any factors that might have impaired the pilot, any environmental factors such as birds or low visibility that may have contributed to the crash, and any mechanical problems with the helicopter, he said.
The Bell 206 helicopter usually has an older engine no longer installed in new helicopters, Robb said.
"We've seen a number of instances where that engine simply failed," Robb said.
J.T. Rhodes knows personally what it's like to receive an organ. "It was truly a gift of life. I never realized how sick I was until I got the transplant," he told CBS affiliate WTEV Jacksonville
Rhodes is a longtime organ donation advocate and president of Transplant Recipients International Organization of Northeast Florida.
When he heard about the helicopter crash he couldn't believe it. "I was in total shock," he WTEV.
Steve Vandergriff, local event director for Donate Life Day, was also shocked. "That's three lives lost that were trying to make the world a better place, trying to do a great thing for other people," Vandergriff said.
According to Vandergriff, more than 110,000 Americans are currently on the U.S. transplant list waiting for an organ, yet only 35 percent of the country are registered donors.
So, when an organ like the one that was ready today becomes available, these missions become life-saving.
The crash and others like it illustrate the delicate nature of transporting organs.
In 1990, a surgeon and an assistant flying to pick up a donor heart for a patient were killed in a plane crash in New Mexico. And in 2007, a twin-engine plane carrying a team of surgeons and technicians along with a set of lungs on ice being brought to a patient already prepped for surgery crashed into the choppy waters of Lake Michigan. Six were killed.
Doctors ultimately got another set of donor lungs that were transplanted into the patient.
