Here's what I have been able to find about the B-29 crash:  

 
November 15, 1957 the plane (44-70039) left Elmendorf AFB at 9:56 a.m. It crashed at 6:22 p.m., after a training radar calibration flight.  The crew were part of the 5040th Radar Evaluation team.  Six were killed and four survived, kept alive by the least injured survivor.  The cause of the accident, it was 27 miles East of it's assumed course.

Information was received from the state (Alaska) Historical Office.
