said Perry Choate, 419th FLTS Electro Optics lead.

  “The importance of this laser mask zone test was to
assure the lasers would not touch any aircraft structure.
The most important reason to keep the lasers from hitting
the aircraft was to guarantee a correct laser range mea-
surement to the intended ground point of interest. If the
laser hit the aircraft, the laser range measurement would

  Two other reasons for keeping the laser from touch-
ing the B-52 is the sensitivity of the internal laser range

to the targeting pod from the aircraft itself. There is also a
nominal ocular hazard distance from where the laser hits
the aircraft surface that could possibly affect the cockpit
area and aircrew.

  In order to integrate the lasers, the 419th test team had

touch aircraft structure, which was labor intensive. This
entailed measuring each of the lasers as test personnel
moved around the aircraft structure.

  “We had to climb on the engines and wing areas to
measure where the lasers were in relation to the aircraft
structure. Once we determined the angles, a safety buf-
fer was added to that initial two-dimensional curve. I

  The result was a list of angles that masked out the B-52
aircraft structure to prevent laser striking aircraft structure

  What made the test challenging is that all three lasers
