An investment banker died with his wife and two children when their small plane crashed on to a busy highway in New Jersey.
Jeffrey Buckalew, 45, his wife Corinne, and their children Jackson and Meriwether, were flying a single-engine Socata TBM-700 aircraft from New Jersey's Teterboro Airport to Atlanta to see relatives.
Mr Buckalew worked for Greenhill & Co in New York. A colleague Rakesh Chawla, 36, was also on board, and also died in the crash.
Mr Buckalew was the registered owner of the plane and an experienced pilot.
Investigators were looking into whether icing on the wings could have caused the crash.
The National Transportation Safety Board said the pilot had, in a seven second call, talked with an air traffic controller about icing shortly before the crash.
They said it was not clear if the call was to report icing had occurred, or to question the location of possible icing conditions.
The plane crashed on Interstate 287 in northern New Jersey. No-one on the ground was injured.
Witnesses described the plane going down out of control with a wing looking like it was breaking off. Eyewitness Sue Bhende said: "I saw the plane taking a nosedive and then a big fireball."
A neighbour of the Buckalew family told the New York Post: “They were a beautiful family. Gorgeous children."
In a statement Greenhill & Co said: “The firm is in deep mourning over the tragic and untimely death of two of its esteemed colleagues and members of Jeff’s family.”
