Ju 88 shot down by U-243 on 11 June 1944

[Laurent Rizzotti]

Hello, I have some questions about a Wekusta Ju 88 shot down by U-243 on 11 June 1944 off Norway.

Here is what I found so far:

During the night of 10-11 June 1944 U-243, that had sailed from Stavanger on 8 June, shot down an approaching aircraft in AN 2911 position. The aircraft flew over boat at a height of 40 meters and was too late in replying with recognition signals. After the aircraft crash it was identified as a Ju 88. The Wekusta 5 reported on 11 June the loss of the Ju 88 D-1 WNr 430678 D7+FN that was lost 200km NW Trondheim, Norway ( in Pl.Qu.06/Ost/8633), with four crew: Ofw. Erich Kubin (pilot), Gefr. Hans Wallenfang (radio) and Gefr. Werner Schnattler (Bw) were posted missing while WD-Insp. Werner Platz (meteorologist) was reported as killed, so probably his crew was found and identified by the submarine crew. According to a source, the submarine rescued another meteorologist, Wd. Ass. Günter Rudolph of Wekusta 3. The U-243 arrived at Bergen on 12 June

My questions:

1) what is a Bw (position of Werner Schnattler in crew) ?

2) has someone the time when U-243 shot down the Ju 88 ?

3) can someone confirm the crew of the Ju 88 ? Either there were two meteorologist aboard, one experienced inspector (Platz) and one less so (Rudoph, as an assistant), either there was a confusion in names.

Thanks in advance
