From; Vom Original zum Modell Junkers Ju-88

That's the shadow of EF.59 exactly in the magazine, Flugzeug Classic 3/2018.

In my opinion Luft 46 = projects only

And I think it had a single engine.

Ok, and with "...Please remember, it's mandatory anyway", I wanted to say:
"Please tell us the sources !"

Hey, NASA
you look like intelligent organisation
you look like someone who would be interested in a bargain.
Wanna buy this rocket, NASA ?*
just $150-90 million launch cost and bring space probe direct to destinations, no need for Gravitational Swing by maneuver

With luft'46,I want to say that this variant could have been produce if the war should go on.

What do you mean with "luft'46" ?
It wasn't a project, but an attempt to create an aircraft similar to the P-38 Droop Snoot, and the document you've
attached gives its role as "Leitflugzeug" (leading aircraft), intended to achieve a high accuracy for horizontal bombing,
as it was fitted with a Lotfe bombing sight.

Perhaps you could mention the sources of those photos/facsimiles ? Please remember, it's mandatory anyway !   ;)
That document given the weights mentions the lower part of the Mistel as "Stoffträger" (from "Sprengstoffträger", carrier
of explosives) and somehow brings us back to the discussion we had here: https://www.secretprojects.co.uk/forum/index.php/topic,23397.0.html
In post #49 there, I tried to sum up the weight of explosives, the fuselage could have been filled with and the results are
quite similar. And so I really doubt the feasibility of that weight of explosives, because of the flyability of the resulting Mistel !

is the A2/U2 variant can be considered as a luft'46? Because we just have two proto on this variant(the V484 and V555):

NASA budget proposal continues debate on when and how to launch Europa Clipper

http://spacenews.com/nasa-budget-proposal-continues-debate-on-when-and-how-to-launch-europa-clipper/

Pork in action.  There are some in congress who want to force NASA to use SLS to launch this mission even though an Atlas V could do it albeit with gravity assist and longer transit time:

"NASA has studied launching Europa Clipper on both SLS and on the most powerful variant of the United Launch Alliance Atlas 5. SLS offers the ability to fly a fast, direct route to Jupiter, with the spacecraft arriving at the planet less than three years after launch. The Atlas 5 would take more than six years to get Europa Clipper to Jupiter, and require flybys of both Venus and Earth to do so."

The argument boils down to $1Billion in exchange for 3 years.  Given all outer planet missions to date have used gravity assist, it's not like we can't stick with this approach at a massive cost savings.  The mission cost itself is $2Billion presumably not including launch.  SLS launch would add 50% more.
