The pilot flew the helicopter that transported Marty Guitierrez and Richard Levine to the site of the aberrant form. However, when they landed, he did not allow Levine to take pictures, even grabbing the camera out of Levine’s hand. Levine saw him later at the San Jose Airport making a phone call to George Baselton ensuring him that Levine had not managed to take pictures. He was possibly working for Biosyn as he mentioned he knew that Site B was an Island, but did not know where specifically.
