Here what I was able to translate from Ruddy Klemm notes, pse note that there were 7 survivors rather than one . Also the route of the JU-52 was rather unusual ,flying
West from Mamaia to BUC ,then further West to Arad and rather continue NNW to destination it headed SE which make me conclude was tasked to first fly to Bulgaria to
drop or collect post or Naval personnel at Varna ( Kriegsmarine Base ) then from there continue to its planned destination .

On May 1944, Rosenbaum was the head of the 30 U- Flotilla for over a year and a half . A month earlier, he tried to organize a flight back home to celebrate his 31st birthday on 11 May.

On the evening of May 9 ,1944 Rosenbaum learns he can board a Ju 52 connecting from Mamaia to Berlin the next day. Despite the mext day schedule he still had the time to organize a small birthday
party with his men. On May 10, as planned he boarded the Ju 52 (PH + OI Werk Nr . 3225 ) which was attached to the postal & transport squadron of the Kriegsmarine.

In total, 15 people boarded the aircraft plus the two pilots of JU-52 bound for Germany. The aircraft took off from Mamaia Suitighol airfield aprox 5:30 am . The weather conditions were CAVOK .
After a refueling stop at Pipera and new briefing , the Ju 52 headed to Arad Delta Airfield for next stop . Here was refueled again and then took off again aprox at 11:00 am.

Most passengers red or slept when tree limbs suddenly scratched the corrugated fuselage of the aircraft . The noise woke up Oblt.z.S . Mertineit who was seated just near Rosenbaum .
Before he could really determine what was going on , the plane hit the ground and exploded . Appearently the Ju 52 penetrated fog and hit the top of a mountain 9 km northwest of
Poletz north of Turnul Severin.

At the impact Olt.z.S. Mertineit was blown clear of the aircraft , wounded but survived along with other six other passengers. Seated on the left, just behind the cockpit was Korvt.Kapt.Helmut
Rosenbaum who was not among the survivors.

Having survived so many dangers at sea, he just died in the wreckage of that plane. A total of 10 soldiers perished in the crash , including the two crew members . When the fog dissipated
it was determined that aircraft missed just by 20 meters the safe altitude in order to clear the mountain’s peak . Two days later , the six sailors killed in that accident were buried in the military
cemetery of Orsova , about 38 km from the crash site . This where Helmut Rosenbaum is burried , far from the sea
which had such influenence on his life.
