Siambanes was a renowned spine surgeon in Tampa and Stone was an Advance Practice Registered Nurse. Both worked for BayCare at St. Joseph's Children's Hospital.

The Federal Aviation Administration released a preliminary report Friday classifying the takeoff crash as accidental.

Impact on the Tampa Bay medical community

What they're saying:

Siambanes was remembered by past and present patients, and colleagues for treating complex pediatric cases of cerebral palsy and scoliosis.

"He took on some of the most aggressive and complicated cases out there, and he transformed children's lives," James Judge, a former colleague said.

Judge says Siambanes was known by a lot of his patients as 'Superman'.

Noelle Delgado says Siambanes performed an intense spinal fusion surgery on her 14-year-old daughter, Olivia, in July.

"He was a miracle worker with what he did," Delgado said.

Beyond the operating room, Siambanes was known for his patient care.

"Bedside manner like no other," Delgado said. "And the moment we met him, we knew that he would be the one that we felt most comfortable."

Melissa Kirk, a former patient, says Siambanes performed her underwent spinal fusion surgery when she was 17 years old.

She says he not only gave her the ability to continue her dancing career through college, but he was a mentor to her. Kirk is now an emergency medicine resident.

"I will carry his bedside manner," she said. "I will do my best to make him proud. I know he wrote me a medical school recommendation, so his name's kind of on me at some point."
