I made some partial reverts on the modiphics soon happened after i dared to post part of the draft. Obsviously i cannot understand how nobody cares nothing until i write in a draft or talk, and cames swiftly to 'collaborate' when the stuff is posed in the main page. 

BTW: the AGARD was led by V.Karman. This was not a marginally information. Bignamini was a test pilot simply decisive for the Gina success. Also this cannot be omitted. Another point, the task of project a light fighter was not a simply one at all, just like to project now a minicar like Opel Smart. These and some other omissions needed to be rettified to make a comple article, that this one of G.91 is far away to be.
