Jeffrey and Jessica Willoughby, two of the plaintiffs suing Cessna Aircraft Company in a civil trial over a 2005 plane crash at Katama Airfield, have settled with the company and are no longer involved in the trial that has been underway in Edgartown for the past three weeks.

The long trial that pitted Cessna Aircraft Company against a pilot who suffered crippling injuries in a 2005 plane crash at Katama airfield ended abruptly Wednesday in a confidential settlement, lawyers said.

After nearly a month of testimony and on the eve of closing arguments, lawyers conferred during a sidebar with Dukes county superior court Judge Cornelius Moriarty 2nd and Alec Naiman, pilot of the Cessna 172-N plane that crashed on June 23, 2005.

The legal saga of Alec Naiman, Jeffrey Willoughby and Jessica Willoughby vs. Cessna Aircraft Company ended abruptly this week, after the three 2005 plane crash victims accepted settlement offers.

A juror in the Cessna plane crash case said Thursday that the case was “a toss-up” and might have resulted in a verdict for either side had it not settled on the eve of jury deliberations.

The female Edgartown resident, who did not want to be identified by name, said the panel bonded during the monthlong trial but abided by the judge’s instructions to refrain from discussing the case or drawing any conclusions until all the evidence had been presented.

Brewster police chief Richard J. Koch Jr. said in a statement Monday that Oulton Hues, 73, of Norwood and Edgartown, and Robert Walker, 68, of Falmouth, were the victims who died in the single-engine plane crash in Cape Cod Bay on Sunday.

Mr. Hues was the pilot and a flight instructor; Mr. Walker was his student and co-owner of the plane, a Piper fixed-wing aircraft.

A training flight that departed from the Vineyard ended in tragedy Sunday when the single-engine plane crashed into the icy waters of Cape Cod Bay, killing flight instructor Oulton Hues of Norwood and Edgartown and his student, Robert Walker of East Falmouth.

A civil trial started today stemming from a 2005 plane crash at Katama Airfield, with jurors hearing from one of the crash survivors and taking a trip to the airfield to look at the plane’s wreckage.

The plane’s pilot, Alec Naiman, and his passengers, Jeffrey and Jessica Willoughby, are suing Cessna Aircraft Company in Dukes County Superior Court, claiming that the accident was the result of faulty rails on the pilot’s seat. Cessna is arguing that the crash was due to pilot error.

A civil trial stemming from a 2005 plane crash at Katama Airfield began this week, with jurors hearing emotional testimony from one of the survivors, venturing to the airfield to examine the plane’s wreckage and pondering technical evidence about key parts of the plane at the center of the case.

Testifying in a crowded makeshift courtroom Thursday, the pilot in a 2005 plane crash at Katama airfield gave his account of the accident that left him confined to a wheelchair without the use of his legs.

“I remember at first my morale was very high,” Alec Naiman — who is deaf and was communicating through a sign-language interpreter — said of his subsequent hospitalization. “I was teasing everybody and flirting with all the nurses.”
