Professional parachute demonstrator Larry Lemaster, an Army veteran with more than 3,000 jumps, died doing what he loved, his wife, Anna Elkins, wrote on Facebook Saturday.

Lemaster was among eleven people killed Friday when authorities said a small plane crashed during a skydiving excursion in Hawaii and erupted into flames. The Hawaii Department of Transportation on Saturday updated the number of fatalities.

“I don’t have an explanation for the utter tragedy that has happened,” Elkins wrote.

“But Larry Lemaster would never want one person to waste a single minute of their life mourning his. He was doing what he loved. We spoke about this on many occasions.”

The Beechcraft BE65 twin-engine plane crashed during taking off Friday evening at Dillingham Airfield on Oahu’s North Shore, the Federal Aviation Administration said.

The wreckage of an aircraft carrying 11 people lies on the ground at Dillingham Airfield in Hawaii.

Elkins said her “heart also goes out to” the Oahu Parachute Center and the loved ones of friends who perished in the crash.

“Today is the worst day of my life. My son has lost his father… He wants you to celebrate his life and your own. Love who you love with great intensity. Do what makes you happy. Be the person you want to be because obviously tomorrow is not guaranteed,” she wrote.

John Hart, a founding member of the Ohio-based parachute demonstration firm Team Fastrax, said Lemaster volunteered time taking wounded combat veterans skydiving.

“There really wasn’t anybody like him,” Hart told CNN Saturday. “He just saw the good in everyone… I’ve never met a person like him, and I probably never will.”

He said he spoke with Elkins and she was on her way to Hawaii. Lemaster, whose last performed with Team Fastrax in the fall, loved sharing the sport as a tandem instructor, Hart said.

The cause of the wreck wasn’t immediately known. The plane was carrying passengers who intended to skydive, and it crashed around 6:30 p.m. at a fence away from the runway, Honolulu Fire Department Chief Manuel P. Neves told reporters Friday night.

The cause of the wreck wasn’t immediately known. The plane was carrying passengers headed for a skydiving excursion before it crashed at a fence away from the runway, Neves said.

Some family members of those aboard were at the airfield when the plane went down, Neves said.

“I am closely following the tragic developments out of Dillingham Airfield this evening,” Honolulu Mayor Kirk Caldwell tweeted. “At this time our thoughts and prayers are with the family and friends of the victims.”

The National Transportation Safety Board has sent a team to Hawaii to investigate the crash.

The airfield is about 35 miles northwest of Honolulu, and is a general aviation airport operated by the state Department of Transportation under a 25-year lease from the US Army.

The state leases 272 acres of the 650-acre Dillingham Military Reservation and operates the single 5,000-foot runway primarily for commercial glider and skydiving operations.
