13/14.02.45 Hptm., with Versuchverbandes OKL airborne radar operator, KIA – in Ar
234 B-2/N V15 (SM+FE) that crashed near Oranienburg when the airfield lights were abruptly switched off causing the a/c to stall. Buried in Lehnitz
These two entries can be tidied (they were killed in same aircraft).
The date is confirmed as 13.02.45, there are photos off their graves at:

Also, the aircraft was not V15, which was WNr.130025, but WNr.140145. SM+FE is correct.
