Sometimes you come across things that you’ve not known of, and all you make out is the fact that you’ve been ignorant of it all the while. Such a gargantuan symbol of my ignorance has been these huge planes gracing the Russian army in the 1930’s, when jet propulsion wasn’t even recognized. Being top secrets of the Russians then, the modern history lovers intend to reconstruct them. Setting high standards in the aviation engineering, the then constructed bomber K-7 must go without telling as to how many propellers must have been used to carry this mesmerizingly giant bird.
