A medical helicopter trying to save a man’s life crashed Sunday in Texas, killing all four people aboard.

The helicopter belonging to PHI Air Medical, a Lafayette, La.-based company, was rushing 58-year-old patient David Disman from a hospital in Huntsville to one in Houston for surgery. Unfortunately, two minutes after the helicopter took off from Huntsville Memorial Hospital (2:45 a.m.), the connection with it was lost and after six hours it was found in the dense Sam Houston National Forest, on a private ranch whose owner wasn’t at home at the time of the crash.

State Trooper John Sampa told the Houston Chronicle that the crash made the helicopter, a Bell 407, disintegrate. “It took down a couple of pine trees.”

The other three people aboard were identified as pilot Wayne Kirby, 63, of Bryan, paramedic Stephanie Waters, 27, of Cedar Park and nurse Jana Bishop of Magnolia who would have turned 29 years on Monday if she had survived the accident. Their bodies were taken for autopsies.

The accident was a “devastating loss” PHI Air Medical’s representative Jonathan Collier said. He further added that the team had had a successful mission several hours before the crash when helping save a 2-year-old child pulled from a swimming pool.

Officials from the national Transportation Safety Board and the Federal Aviation Administration are investigating the cause of the accident, which seemed awkward, since the weather was fine and there was no apparent distress call.

Moreover, pilot Kirby had 30 years’ experience within PHI, including flights in Antarctica and Africa. Bishop had been with the company for three year while Walters for two.

This is a second accident involving a medical helicopter in two weeks. On May 29, a medical helicopter crashed on the roof of the 11-story Spectrum Health Butterworth Hospital, busting into flames. Fortunately, the two people aboard managed to escape before the helicopter burst on fire.
