Who flew with Kubyshkin in Ar 234 WNr. 140355?
 

Ar 234 B-2bs were converted to Ar 234 B-2/Ns in three phases:

First, the camera compartments were removed to create a 'funkerraum' which would contain the apparatus and scope for a radar operator who sat in the rear fuselage.

Second, the aircraft would be sent to E-Stelle Werneuchen where the antenna and apparatus of the FuG 218 and night flying aids would be installed.

Finally, it would be sent to Oranienburg where a 'Magirusbombe containing two MG 151s would be installed under the belly.

In the first stage, the radar operator's cabin was given what Smith etal. in On Special Missions, (2003), p. 127 call " the circular [port and starboard] Plexiglas viewing port" with interior photos at the bottom of the page.

In this photo of WNr. 140355, the "viewing port" seen in the middle of the Balkan Kreuz is clear proof that this aircraft had completed stage one of the conversion.

Therefore, I would like to know if there was a second person in 140355 when Kubyshkin made five test flights in January/February of 1946?
