A picture from the 1993 Aviation Week & Space Technology Photo Contest.
This came second in the Military category. The plane
is ejecting flares during a test of an infrared missile warning and self-protection
system installed on a C-130 Hercules. The trailing vortices formed in
the wake are clearly visible. The size of these vortices is related to
the lift produced by the wings, and the photograph suggests that the aircraft
was climbing during this maneuver. See also firing sequence and
