Also killed were Nathan W. Prekup, 33, of Seattle, and David W. Newton, 67, of Wichita, Kansas.

According to A donation siteScott Brenneman leaves behind “a loving family, a loving dog, and many friends and colleagues in the aviation community.”
Raisbeck leased a Cessna Grand Caravan 208B EX single-engine aircraft to collect “baseline aircraft performance data,” company president Hal Chrisman said in a statement.
According to the National Transportation Safety Board, the plane crashed in an agricultural field near Harvey Field Airport.
The plane took off from Renton around 9:30 a.m., the federal agency said. According to one of the eyewitnesses, about an hour later, the plane’s right wing fell off, causing the plane to spiral down to the ground. The wing was found about 200 yards from the wreckage, the NTSB said.
The Federal Aviation Administration and the NTSB are investigating the crash.
A preliminary report will be released in two to three weeks, and the investigation will be completed in 12 to 24 months, the NTSB said.
