I have two 154's losses for which I'd like to get more details if anyone of you can help:

03 June 1942, Sgt D.J. King was posted missing and was taken prisoner. Seems that no engagement with the Luftwaffe took place. What was the cause then? Engine trouble?
21 June 1942, F/L G.T. Hugill was shot down by Fw190s but the ORB gives a wrong serial (BM323). He survived to become a PoW. What is the right aircraft?

Many thanks for helping
