USAF to Purchase 20 Embraer A-29 Super Tucano Aircraft

As reported by Embraer earlier today, the USAF (in partnership with the Sierra Nevada Corporation) will be acquiring 20 Super Tucanos. The aircraft are said to provide "advanced flight training, aerial reconnaissance and light air support operations".

It won't be the first time Super Tucanos have operated in the US. XE Aviation (formerly Blackwater) has flown N314TG (photo) and displayed it at the 2011 Reno Air Races in Nevada. XE Aviation also has a Pilatus PC-6 registered under N181DA (photo).

Super Tucanos have also been photographed under military registrations, although nobody seems certain whether these are different airframes, or simply N314TG with different markings. Indeed, a thread on Scramble points out that the military registration seems to be a re-purposed MH-53E registration, perhaps to keep the aircraft (and possibly the "Imminent Fury" program) under wraps:

Another photo on Flickr shows the same airframe equipped with what appear to be guns or rocket pods underwing.

Boeing 787 Wing Flex Animation

After reading Guy Norris' great article on the Boeing 787's wing flex, I thought it would be interesting to animate the three graphics he posted.

Here, we see the 787 wing in three stages - at rest, at a normal 1g load during cruise flight, and at the ultimate load, just before failure:

It's interesting to note that in normal cruise flight, the wing flex is such that the wingtips are above the top of the fuselage.
