The only people trying to doctor the truth here are the nay-sayers who are trying to deny photographs, who produce no evidence that photos were doctored and who ignore log book entries of Ju 390 pilots, WW2 reports of interrogations and then think themselves smart because they twisted truth.
These nay sayers themselves were never there.... Voss Hirschfeld, Speer and Eisenmann were.
Do Davide Pastore and phylo_roadking suggest all these people were wrong or lying ?
Dr Wilhem Voss was there and saw a Ju390 operating in April 1945 3 months after the Ju 390 was destroyed at dessau in an Allied air attack. Gosh that's a great voodoo trick.
Wolfgang Hirschfeld was there and wrote in his book "Atlantik Farewell: Das Letzte U-boot" about the Ju 390 flying to Japan in 1945 after the destruction of the Ju 390 at Dessau.
Albert Speer was there and wrote in his memoirs after the war about the Ju 390 flight to Japan. He only happened to be one of the most important and well informed men in Germany. I suppose he was wrong too ?
Oberleutnant Eisenmann only happened to have two flights in the Ju-390 in his logbook for 9 February 1945 a month after the destruction of a Ju 390 laying derelicty at Dessau since November.
Igor Witkowski only happened to find at the Berlin Document Centre, authentic SS reports from 1945 of the Ju-390's flights in April 1945 and just because Davide Pastore and phylo_roadking say so these reports must be untrue ... now that's getting way psychotic.
The Ju 390 did not suffer from structural weakness. The Ju 90 V6 which it was converted from was underpowered with four BMW132 engines of 660hp and wings much shorter than the standard Ju 290 wings which did not appear until the Ju-90 V8 airframe. As any pilot knows small wings equate high wing loading and high stall speeds. Coupled with weak engines, this also limited the Ju-90 V6's take off weight. Twits who have never in their lives been pilots have learned that the Ju 90 V6 was limited in take off weight and reinterpreted the information without grasping the aeronautical issues to falsely infer the aircraft was weak. the Ju 90 V6 was identical to the Ju 90 V7 in these photos below:
After Ju 90 V6 was converted to Ju 390 V1 and Ju 90 V11 was converted to Ju 390 V2, the wings were considerably enlarged and the engines were much more powerful BMW801D types with three times the power.
