Monumental Helicopters is owned by Towson-based Sierra Delta LLC. On Tuesday, Christia Raborn, Sierra Delta's owner, said her company employed Jenny on a contractual basis to fly tour helicopters for Monumental, but that Jenny had been on vacation for several weeks when the accident occurred.
The helicopter involved was not leased, registered or owned by Sierra Delta, Raborn said, and the flight was not chartered by either company.
"We know very little about it," she said of the crash.
She declined to comment further out of respect for the families involved.
Monumental Helicopters is located at Tipton Airport in Fort Meade, a runway that leases hangars to small companies.
Curtis Zellner, the airport's operations supervisor, said Jenny was a regular face on the grounds, popping into the airport offices often to take care of business for Monumental and chat with the office staff.
"He had a nice personality. He was friendly with everybody," Zellner said.
Several staff members at the office who declined to give their names shared similar sentiments. They also said they had seen Jenny late last week, preparing for a trip.
People who frequent small airports develop a bond, Zellner and others at Tipton said, and become close. Everyone in the office was hit hard by Jenny's death and thinking about the families involved, Zellner said.
"My wife worries about me when I go up," Zellner said.
Josh Jenny said his family learned of the accident around 5 p.m. Sunday, and he made the nearly two-hour drive that night with his father from their Kintnersville, Pa., home to a spot near the crash scene where "we confirmed the worst."
The wreckage of the heavily fragmented helicopter was discovered around 2 p.m. that day in a rugged, wooded area near Noxen, Pa.
"Dave and I would talk every day," Josh Jenny said. "Every time we talked on the phone, it was so invigorating. The plan was for me to get my pilot's license so I could begin flying with him."
David Jenny, the son of a nurse and a forklift operator, moved to Maryland about five years ago. He was a 2001 graduate of Palisades High School in Kintnersville, 45 miles north of Philadelphia, and went on to earn an associate's degree in computer science from Bucks County Community College, Josh Jenny said.
Josh Jenny said his brother had produced websites and turned a fascination with cars into a business creating a hybrid between Toyota MR2s with an Asian motor and an American body. While he trained to become a helicopter pilot, he worked in fugitive recovery for an Fairfax, Va.-based bail bond firm.
"He was entrepreneurial — the only job he had was washing dishes at a pizza place when he was 14 and he had enough of answering to someone else," Josh Jenny said. "I learned quite a bit from him."
David Jenny inherited his love of flying from his grandfather, who was a pilot, his brother said. Hanging in their family workshop is a photo of their grandfather as a 10-year-old in a toy airplane their great-grandfather built in the 1920s.
The brothers were raised along the Delaware River in Bucks County, where their family raised Siberian husky sled dogs for racing. And as they grew into adults, they tried to outdo each other driving go-karts and boats and race cars, Josh Jenny said.
"It was sort of like a sibling rivalry to see who would operate the most incredible piece of machinery. I always felt behind the eight-ball," Josh Jenny said.
Three years ago when David Jenny hovered over the family home in a helicopter, Josh Jenny recalled racing out and seeing his brother, knowing he'd just lost for good.
"He just had an incredible fortitude to learn new things," Josh Jenny said. "He was never afraid to be the person to just dive into something. He had tremendous ambitions. We were all very proud of him. He lived life to the fullest."
Services for David Jenny will be private.
