The Thornbury crew arrived at Rattlesden on March 16 and were assigned to the 710th Squadron on the following day (Special Order No. 67, 17 Mar 44; 447bg Ref B0558-0989).  Within two weeks they had completed orientation and were flying combat missions.

On April 13, the group experienced intense flak en-route to the target, forcing some planes to abort and return to base.  Over the target itself, a Messerschmitt factory in northern Germany, the formation again encountered heavy flak, and several more aircraft were severely damaged.  Three of those, including Thornbury's 42-107021 -- less than a month old -- were able to make Dubendorf Airfield in Northern Switzerland.  

The group's summary report of the mission gives little in the way of detail:

During their internment, the crew was quartered in and around Davos, Switzerland.  Lts Joseph (Ray) Thornbury and George Filush escaped in September 1944.  Dante Rich also escaped.  The rest of the crew was repatriated in 1945.
