A newly-qualified RAF pilot was killed when an articulated lorry ploughed into the back of his car, a court has heard.
Scott McConnell, 26, had stopped on the M40 near Warwick to help in a separate crash and sat in his VW Golf with his hazard lights on.
HGV driver Malcolm Clarkson, who the court heard was speaking to his mother on a hands-free phone, braked just a second before impact.
Clarkson, 44 and of Cat Tail Lane, Southport, Merseyside, was jailed for three-and-a-half years and banned from driving for six years and nine months this week.
He had admitted causing death by dangerous driving at an earlier hearing.
Warwick Crown Court heard that Mr McConnell was an air crew sergeant in the RAF, having graduated from the Defence Helicopter Flying School at RAF Shawbury, and was due to begin a posting in Chinook helicopter at RAF Benson when the crash happened on November 19, 2019.
