A new (old) launch technique we need to consider.

Really interesting stuff, especially for hang glider pilots - four blog posts about recent engineering analysis of Pterosaur aerodynamics.
The blog comments are a must-read.

Links to all four posts here: http://pterosaur-net.blogspot.com/2014/01/pterosaur-aerodynamics-at-gwu.html
