The crew of this US Navy E-6B Mercury (162784) is snapped here conducting a walk-around check of their aircraft as they prepare to button it up for an RON stay at RNO. * My sincere Thanks to USN Lt Gore for the additional info he provided about this aircraft. Lt. Gore stated that this particular aircraft was one of the last 707s (see ** below) to come off the Boeing production line. According to the Lt., only a few more were built after this one. ** NOTE: The E-6 is one of the military variants of Boeing's 707-320.
