NIAT 2.5 ST Freighty amphibious cargo/passenger aircraft project

[ChuckAnderson]

Hi Everyone!

I found this picture of an interesting looking transport aircraft, with a rather unusual way to load cargo.
Can someone help to identifiy this aircraft please?
Thanks!

I think that was a proposed Russian design, I recall seeing it in a past edition of either JAWA or Brassey's. I want to say Aeroprogress, but not sure.

Perhaps just an accidental similarity to the Beriev Be-112 proposal ?
(picture from the book Beriev aircraft 1968-2002, sorry, for more details
regarding this book, please ask boxkite, I can't read cyrrilic letters ! : )

Hi,

I think it was Orel aircraft.

 

[boxkite]

It's a Russian design named NIAT 2.5 ST Freighty. I found it in JAWA 1997-1998 when I borrowed the book a few years ago. Sorry I've forgotten to save the description then.
