In response to your first query...
This was the timeline of what took place with the USAF--
April 22, 2008: the USAF evaluated the FTV at Mr. Reed and expressed a desire to develop it for their use. (CEO memo 5/1)
May 31, 2008: Torvec received a purchase order for a vehicle for $106,000. This included a "sole source justification" memo stating that after extensive research it concluded Torvec had the only tracked vehicle that met its specifications. (CEO memo 6/16)
In the same memo it states the USAF invited Torvec to demonstrate the vehicle to the Dept of Homeland Security, FEMA, Dept of Interior, and others.
(--At the time I remarked that for a government department this is breath-taking speed--)
Oct 7, 2008: USAF "purchased and took delivery" of the vehicle.(CEO memo 8/6)
The time spent on evaluation is totally reasonable. Their interest is demonstrated by a mere 40-day gap between seeing and ordering. This is the military??
