REASON FOR LOSS:
Took off at 22:44 hrs on a two (2) part bombing raid on the railway yards at La Chapelle, with an interval of one hour. 269 aircraft taking part. Bombing was considered very accurate as they were using a new target marking method. No reports were available as to actual damage and casualties in the target area.

ND573 was claimed by Maj. Wolfgang Thimmig, his 20th Abschuss from Stab NJG4 as a probable Lancaster near Morsang, 7 km NNE of Bretigny (i.Zus.Arb.) at 3,600m at 00:40hrs
Note: also claimed by Flak of gem. Flak Abt 496. (Lancaster Antony 00:35). Flak claimed ‘VNE’. The victory for Maj. Thimmig was confirmed on the 6th July 1944. (Nachtjagd Combat Archive (23 June - 22 September) 1943 Part 2 - Theo Boiten)
Obstlt. Thimmig survived the war with 22 night and 1 day confirmed Abschüsse, He became West Germany’s Military Attache in Sweden. He passed away on the 6th November 1976 in Stockholm, Sweden, aged 64. (Luftwaffe ACES - Biographies and Victory Claims (Mathews and Foreman) - Volume 4)
The Missing Research and Enquiry Unit (No 1 MREU, No. 3 Section) tried to establish the location of the graves for these crew members and a report sent into the Air Ministry on the 7th June 1946. They established that a four engined aircraft had crashed in the Morsang-Sur-Orge area at 00:30 hrs on the 21st April 1944. The team visited the crash site but as it had since been cultivated no remains of the aircraft had been found apart from a relief valve with a serial number S/A/270 R.7622 by a local man Monsieur Cicchelero. No one in the area could state how many bodies were found but that they thought they had been taken away by the Germans to Bretigny-Sur-Orge. The team inspected that cemetery but nothing corresponded to this crash.
A further investigation took place on the 9th May 1947 to try and establish further information. Nothing definite was established and it was concluded that very few remains were found at the time of the crash as the aircraft had exploded. The Germans were unable to recover the engines after the crash as they were buried too deep. They stated that the remains found were possibly buried with others at Clichy cemetery.
One witness stated that he thought the pilot had tried to find open ground to crash to avoid hitting nearby homes.
