I asked for reliable sources, not more gossip. The following may or may not be reliable, but it is referenced.
On May 14, 1943 a Lockheed PV-1 Ventura, Bureau Number (BuNo) 33142, which operated out of NAS Seattle, crashed into Mount Rose, in the Olympic National Forest in Washington State, roughly 40 miles west of Seattle. All five crew were killed. http://www.dvrbs.com/monuments/berlin/BerlinWW2-FrankHBlanck.htm
