An alligator that made its way onto the runway at MacDill Air Force Base in Tampa has been moved to a nearby river, officials said. The large reptile was spotted Monday morning next to the landing gear of a KC-135 aerial refueling aircraft, base officials posted on Facebook. Officers with the Florida Fish and Wildlife Conservation Commission responded a shot time later. They captured the animal and then released it into the nearby Hillsborough River. According to wildlife officials, alligators become more likely to wander into unfamiliar territory in April as they search for mates.
