The NB-52A 52-0003 and NB-52B 52-0008 that launched the North American X-15 rocket planes carrried mission marks commemorating each flight. Horizontal X-15 silhouettes represented captive carry flights. Upward tilted silhouettes represented powered flights. Over the history of their operations, the mission marks were occasionally revised to make room for more.
May 1959: The first four X-15 mission marks represented four captive carry flights conducted in April 1959.
October 1960
April 1961: The NB-52A was flown to Boeing’s facilities at Wichita, Kansas in early 1961 for maintenance. While it was in the hands of Boeing, it was given a complete makeover. The first X-15 launch conducted after repainting was the fifteenth flight of the second X-15 on April 21, 1961. The X-15 mission marks were moved closer to the leading edge of the wing to make room for more.
May 1962
May 1963: While the NB-52A was at the Boeing facility in Wichita, Kansas from December 1962 to April 1963, the second set of X-15 mission marks was replaced with a more compact set.
May 1965: A fourth set of mission marks was made more compact by stacking consecutive captive carry flight marks.
October 1969: The mission marks of the NB-52A as they appeared when it was retired on October 19, 1969.

(MASDC) at Davis Monthan AFB near Tucson, Arizona on April 24, 1972.
May 1960: The original mission marks of the NB-52B were applied below the 36-inch tall U.S. AIR FORCE.
May 1961
November 1961: Between the Open House on May 21 and the twenty-first flight of the X-15-2 on November 9, 1961, the thirty-six inch tall “U. S. AIR FORCE” lettering on the fuselage of the NB-52B was changed to smaller twenty-four inch tall letters. The X-15 mission marks were moved to a location between the leading edge of the wing and the astrodome. A stack of red mission marks below the leading edge of the wing represented flights with an inertial systems pod made from the external fuel tank of a North American F-107 that simulated the navigation functions of the X-15.
May 1963: The second set of mission marks was replaced with a more compact set.
July 1963
October 1965: The X-15 mission marks were revised a third time. The inertial systems pod mission marks were moved to the top row of marks.

May 1971: Sometime before May 1970, the X-15 mission marks were stripped and replaced with three marks for the last powered fligh and two captive carry missions. Three sets of marks were added for the X-24A, M2-F2, and HL-10 lifting bodies. Bruce Peterson’s crash landing in the M2-F2 was represented by an inverted mark.
December 1974: New mission marks were installed sometime before May 1973. The X-15, M2-F2, HL-10, and X-24A were each represented by a single mission mark and the number of flights launched from the NB-52B. M2-F3 and F-15 RPRV mission marks were added to the left of the mission tallies and mission marks for subsequent programs continued along the side of the fuselage.

April 2001: The original Orbital Sciences Pegasus mission marks were a silhouette of a winged horse with red flaming rocket exhaust.
The NB-52B on June 29, 2001. Sometime between November 2000 and June 2001 the Pegasus, and X-38 Space Station Crew Return Vehicle mission marks were rearranged. The winged horse mission marks were replaced with planform sihouettes of the actual Pegasus rocket.
November 2004: The retirement of the NB-52B was commemorated with "T-THA...T-THA...T-THAT'S ALL FOLKS!" to the left of the mission marks.
Many of the missions flown by the NB-52B are represented by the symbols in the rectangles at the right: 140 X-15 flights, 17 M2-F2 flights, 37 HL-10 flights, 27 X-24A flights, 41 F-15 RPRV flights, 9 SRB/DTV flights, and 29 F-15/SRV flights.
Thirty-five M2-F3 marks appear to the left of the mission tallys. Twenty-five marks include a red triangle indicating a rocket-powered flight. The NB-52B first carried the M2-F3 on May 22, 1970. The last M2-F3 launch occurred on December 20, 1972.
Forty-seven X-24B marks appear to the left of the M2-F3 marks. Although only two X-24B marks include the red triangle indicating a rocket-powered flight, the X-24B flew twelve powered flights. The NB-52B first carried the X-24B on July 19, 1973. The last X-24B launch occurred on November 26, 1975. Floodlights can be seen on either side of the X-24B marks.
The NB-52B has accumulated a collection of stickers below the M2-F3 marks. These include badges from the Experimental Aircraft Association, Tinker Air Force Base, Phoenix Air (illegible) Copperheads, 337th Test Squadron, MAINEiacs, 2953 CLSS, 931st Air Refueling Group at McConnell Air Force Base, Boeing Fire Department, and the 23rd Bomb Squadron. The blue sticker at the lower right is no longer readable, but it is the badge of the 562nd Tactical Fighter Training Squadron, which was based at the former George Air Force Base.

Two B-52 silhouettes at center represent Wake Vortex tests and one represents an F-16 Target Test. Ten marks represent flights by the F-15 Spin Research Vehicles, although the three vehicles were launched twenty-six times. The first F-15 SRV flight was launched on November 29, 1977 and the last was launched on July 15, 1981.
The NB-52B flew past a tower equipped with meteorological instruments near Idaho Falls, Idaho in October and December 1977. I have not determined the date of the F-16 Target Test.
Thirteen marks represent the Shuttle Reusable Booster/Drop Test Vehicle (SRB/DTV). Two horizontal silhouettes at upper right indicate captive carry flights flown on June 10, 1977. Below those silhouettes are two more representing the first series of six drops of the SRB/DTV, which began on June 15, 1977 and ended on September 12, 1978.
The nine SRB/DTV marks to the left represent a second series of drops of the SRB/DTV. Three large stabilizing fins were added to the SRB/DTV. The SRB/DTV silhouettes for the second series of drops show the fins. The first drop was scheduled for February 23, 1983, but the rear hooks on the X-15 pylon failed as the NB-52B was taxiing. The horizontal silhouette with the hook at the front represents that incident. The first of eight drops in the second series was flown on September 16, 1983. The last was flown on March 20, 1985. The parachutes separated from the SRB/DTV on one flight, which is represented by a silhouette with a ground line and Joshua Trees on each side.
This B-52 silhouette also represents the day that the hooks failed on the X-15 pylon. Very small letters underneath the silhouette read "T.F.H.B." (The F***ing Hook Broke).
Thirteen silhouettes at right represent flights of modified Ryan BQM-34 Firebee II drones in support of the Drones for Aeroelastic Structures Testing (DAST) program.
The two marks at the top represent flights of a nearly stock Firebee II. Three captive-carry flights were flown in November and December 1975, and July 1977. The Firebee II was launched from the NB-52B once on July 28, 1977.
The next two marks represent the Firebee II equipped with an instrumented wing called "Blue Streak". The NB-52B made one captive-carry flight and one launch of the Blue Streak in March 1979.
The six lower marks and two to the left represent the Drones for Aeroelastic Structures Testing. The first DAST drone was carried on the NB-52B for the first time on September 14, 1979. It was launched three times, the first time on October 2, 1979 and the last time on June 12, 1980. On the last flight, its right wing failed and the drone crashed in the desert. That flight is represented by the mark directly below the three bomb bay vents.
The second DAST drone was carried on its first captive carry flight on October 29, 1982. It was launched from the NB-52B once on November 3, 1982. DAST II made two more captive-carry flights in early 1983, but all subsequent launches were made from a Navy Lockheed DC-130A Hercules. The bottom silhouette in the left column is said to represent a launch of the DAST II drone from the DC-130A.
Nine marks to the left of the bomb bay vents represent drops of the F-111 Parachute Test Vehicle (PTV) from the bomb bay of the NB-52B. Increases in the weight of the F-111 escape module resulted in a requirement for a new parachute recovery system. The first series of eight PTV drops ran from February 1979 to August 1979.
The black rectangle appears to be a camera housing. There is a photo resolution target in the white rectangle above the camera housing. It looks like there once was a mirror on the X-15 pylon that reflected an image of the photo resolution target to the camera. I do not know the reason.
I have not identified the four bat-like marks below the camera housing.
Five more F-111 PTV marks appear to the left of the camera housing and photo target. A second test series of eleven PTV drops was conducted in 1982. The first drop of the second test series was flown on March 3, 1982. The last drop of the second PTV test series was flown in November 1982.
Thirty-eight silhouettes represent the two Highly Maneuverable Aircraft Technology (HiMAT) drones. Twenty-seven silhouettes have red flames indicating a powered flight. The NB-52B launched the first HiMAT drone fourteen times and the second HiMAT drone 12 times. The first captive-carry HiMAT flight was flown on July 11, 1979. The first HiMAT launch occurred on July 27, 1979 and the last occurred on January 12, 1983.
Nine marks represent a third series of drops of the SRB/DTV. I do not know the dates of those tests.
Twenty-three more F-111 PTV drop test marks appear below and to the left of the SRB/DTV marks. A third series of twelve PTV drops was conducted from July 7, 1987 to November 9, 1988. A fourth series of eleven PTV drops began in May 1989. The last drop of the fourth test series was flown in February 1990. Seven of the marks appear to show reefed parachutes.
One mark represents a parachute failure that resulted in the PTV impacting in the desert at the China Lake Naval Air Weapons Station.
Nine Orbital Sciences Pegasus sihouettes represent three captive carry flights and six launches. The NB-52B was the first airplane to launch a satellite into orbit on April 5, 1990. The NB-52B made its last Pegasus launch on August 3, 1994.
The original mission marks for the Pegasus were silhouettes of a winged horse. In June 2001, those marks were removed and replaced with silhouettes of the rocket. Other marks were removed and replaced at that time. Scuff marks can be seen where the old marks were removed.
Thirty four marks represent flights that the NB-52B made with a pair of J85 jet engines mounted on a pallet in the bomb bay to test fuel additives for the reduction of emissions of pullutants during supersonic cruise flight. The fuel additive tests were conducted in 1994 and 1995. The X-15 pylon was removed and a close-out structure was installed in the notch in the trailing edge of the wing for these tests.
Eight space shuttle silhouettes represent tests of the drag chute used to decelerate the orbiters when they land. These tests were high-speed taxi runs at speeds up to 192 knots. Four tests were conducted on Rogers Dry Lake in July and August 1990. Four tests were conducted on Runway 22 in Septebmer and October 1990. The bottom silhouette represents a test in which the drag chute separated from the NB-52B.
Fifteen marks represent more tests of the F-111 PTV. A new 85-foot diameter ring sail parachute system was developed for the F-111 crew module. A fifth series of four drops of the PTV were flown to test the new parachute in February and March 1991. A sixth series of ten drops was conducted from June 1991 to November 1991. A seventh series of five drops began in March 1992.
Five bomb bay vents can be seen in this picture. They open to the rear.
Twenty silhouettes represent twelve captive-carry flights and eight drops of the two X-38 Crew Return Vehicles. The NB-52B first carried the X-38 V-131 on August 2, 1997 and first launched it on March 12, 1998. The NB-52B first launched the X-38 V-132 on March 5, 1999. X-38 V-131 was modified and returned to flight as X-38 V-131R on November 2, 2000. The NB-52B last dropped X-38 V-131R on December 13, 2001.
Six silhouettes represent three captive-carry flights and three launches of the X-43A Hyper-X. The first captive-carry flight was flown on April 28, 2001 and the first Hyper-X stack was launched on June 2, 2001. The silhouette for that flight shows the stabilizers breaking away from the modified Pegasus booster. Each of the successful launches of the X-43A was preceded by a captive-carry flight. The final flight of the NB-52B launched the third Hyper-X stack on November 16, 2004.
