id its the same one I'm thinking about it was lost in a collision with a escort which was doing aerobatics around itThose impressive photo's are not from the real aircraft. Those are later "fantasies".
However, the Kalinin K-7 was reality, but crashed and killed 14 people.
The inventor, Mr. Kalinin, was executed as "enemy of the state". I think it was because his machine didn't work, not espionage.
Now, how'z't for incentive to get the F-35 to work (giggle).
