However, the intention of the program was for the QF-106 to survive repeated engagements with air-to-air missiles, to make it possible for each QF-106 to last as long as possible before it was destroyed. The last shoot down of a QF-106 (57-2524) took place at Holloman AFB on February 20, 1997. 

The QF-106 was replaced by QF-4 Phantom drones, which will eventually be replaced by something else.

Almost 2/3, approx 199 aircraft, of all the Sixes produced were converted to QF-106 Aerial Target Drones under the 'Pacer Six' Program assigned to the 475th Weapons Evaluation Group (WEG), most expended by the 82d Tactical Aerial Targets Squadron (TATS) at Tyndall AFB Florida. In the course of active operations QF106 drone ops, which extended to January of 1998, there were several flyable survivors which were able to return to AMARC for storage.

Swamp Things Last Survivors - Final Chapter of the QF-106 Drones

By CMSgt (Ret) Dick Lewis

At the end of the 'Pacer Six' Drone Program there were a few non-flying aircraft left on the Tyndall ramp, 7 F-106 airframes parked in a part of the Tyndall AFB ramp known as the 'Swamp', a temp storage location usually for aircraft in an unflyable condition.

The last 7 F-106's parked in the swamp became known as Swamp Things.  Below is a list of the aircraft tail numbers, the last unit they flew with (prior to drones) and the reason for them now being non-flyers. 

F-106B 57-2509 from the 159 FIS - Wire bundle fire in lower electronics bay-no structural damage from fire
F-106B 57-2517 from the 186 FIS - Crash Damage
F-106B 57-2543 from the ADWC - Nose Gear Damage
F-106B 57-2545 from the 5 FIS - Cracked Intake Duct
F-106A 58-0786 from the 159 FIS - Cracked Wing Spar
F-106A 59-0047 from the 119 FIS - Cracked Wing Spar
F-106A 59-0105 from the 5 FIS - Cracked Wing Spar

On 11 Mar 2001 - Trucked to Camp Blanding FL for static displayF-106A 59-0105 was trucked off to 

In the spring of 1998, the last of the 'flyable' QF-106's departed Tyndall AFB for their final destinations. Aircraft 59-0158, 59-0043 and 58-0774 flew to the boneyard at Davis-Monthan AFB, while 59-0023 flew to the museum at Dover AFB.

Left behind, were these seven non-flyable QF-106's sadly relegated to the backline "Swamp" storage area.

However, in early 1999, an unnamed party was contracted to remove the Swamper's and truck them to El Paso, TX, purportedly for air-museum displays. After three aircraft were prepared for transportation, work was halted due to a contract dispute. The aircraft were secured from wind and weather damage, the tools and equipment were put in storage and the work crew disbanded.

In April 2000 six of the seven Swamp Things finally departed Tyndall AFB, FL on several flatbed 18 wheelers bound for El Paso, TX.  They were F-106B's 57-2509, 57-2517, 57-2543, 57-2545 and F-106A's 58-0786, 59-0047.

They had been purchase via subsequent negotiation by a private aviation enterprise based in El Paso, TX by David Tokof of GRECO-AIR, later Westernair, and a tentative deal was struck with DRMS to sell the aircraft for purposes of restoring them as non-flying, museum-display grade aircraft.  Originally they were planned for restoration with one possibly put back to flyable status, but they were all already de-milled.  Only one of the airframes had a 'date plate', 57-2509.  The other aircraft 'date plates' were evidently removed at Tyndall AFB. All control stick grips missing. 3 Ejection seats included. Cockpits had some instruments still in them. No canopy actuators as they were part of the ejection system which were removed. New longerons etc. manufactured to attach tails as it came from factory. Enough new parts for 2 complete static display aircraft. One J75-P-19 Engine minus tail pipe, nozzle-afterburner diffuser is on the engine. Tail pipe shroud on-hand. No records, but engine is from an F-106.

Unfortunately David passed away so the restoration plans for these jets changed. 

In Mar 2004 the "El Paso Birds" in the private hands of WESTERNAIR Inc., began the process to sell them rather than restore them.  These aircraft were indeed eventually all sold off and thankfully to locations who would restore them for display. 

On 12 Dec 2016 the LAST two El Paso F-106's were sold -- there were no more remaining in El Paso. F-106B 57-2509 and 57-2543 departed El Paso on 14 Dec 2016 heading to their new homes at the Palm Springs Air Museum and Excelsior High School in the Los Angeles area. Searching for more details from Dick Durand of Western Air Inc.

There were also a few non-flying airframes left on the Tyndall ramp at the end of the 'Pacer Six' Program (7 aircraft), as well, and originally they were parked in that part of the Tyndall AFB ramp known as the 'Swamp', although in unflyable condition.

Purchase of these remaining airframes was subsequently negotiated by a private aviation enterprise based in Texas (David Tokoff's GRECO-AIR in El Paso) and a tentative deal was struck with DRMS to sell the aircraft for purposes of restoring them as non-flying, museum-display grade aircraft. One of these aircraft was reportedly ear-marked for restoration as a fully operational flying specimen, although it appears that perhaps two of them may have been fully restored at this time for flight (including a two-seat B model); however, due to the fact that stringent 'de-mil' requirements for combat aircraft require cutting the airframe structural members to render them incapable of further flight applications, this stalled the whole purchase package for some time.

In Mar 2004 the non-flying survivors had all been trucked from the Tyndall ramp and shipped to GRECO-AIR's El Paso base of operations, where most of them awaited restoration. Since then, and as recent as Nov 2013, the "El Paso Birds" as most refer to them now are in the private hands of WESTERNAIR Inc. and are in the process of being sold.

USAF "Full Scale Aerial Targets" Drone Program History

By Col Robert "Buzz Sawyer
   

In the early 1970's the U.S. Air Force started the "Full Scale Aerial Targets" (FSAT) program, aimed at providing the test community with realistic targets for anti-aircraft weapons. The targets needed to be similar in size and performance to "threat" aircraft. Rather than building something from scratch, the service decided to "reclaim" USAF fighters from storage. As older military aircraft get too expensive to support, or their capabilities become obsolete, they may be sold to other countries, "scrapped" for their parts and recyclable components, or put in "storage" at the Air Force's "Aircraft Maintenance and Reclamation Center" (AMARC) at Davis-Monthan Air Force Base in Tucson, Arizona. These "storage" aircraft in the "Bone Yard" became the source for the FSAT program, as they are today.

The first target was the F-102 "Delta Dagger," which was flown from about 1974 to about 1984. This 1950's vintage fighter-interceptor, known as the "Deuce" by its pilots and maintainers, was built in limited quantities. The Deuce was replaced by the F-100 "Super Sabre" beginning its phase-in around 1983. Also known as "The Hun," the supply of F-100s was also limited, and was followed by the F-106 "Delta Dart" which became operational as an FSAT in 1991. The last F-106s were flown at Tyndall AFB in Florida, in early 1998. In 1996, the F-4 "Phantom II" started pulling duty as an FSAT. A large supply of F-4s exists, and should last for the next couple of decades.

With the sole purpose of being shot at by "killer" missiles, there weren't many volunteer pilots to fly these target fighters. A system was designed to allow these jets to be flown from the ground by remote control. Once modified to be flown by remote control, these old fighters and interceptors are redesignated with a "Q" in front of their former designation, thus: QF-102, QF-100, QF-106, and QF-4. The aircraft are taken out of "storage" and made airworthy and flyable by the personnel at AMARC. The jets are then flown to a civilian facility (currently Mojave, California, for the QF-4) where all the remote control components are installed. They're then flown to Tyndall AFB, Florida, where the first remote control flight is attempted/accomplished, and "accepted" by the U.S. Air Force for duty as FSATs. Since the program's inception in the early 1970s, two Air Force bases have flown FSATs: Tyndall AFB near Panama City, Florida, flying on ranges over the Gulf of Mexico (W-151 and W-470), and Holloman AFB near Alamogordo, New Mexico, flying over the White Sands Missile Range. The bulk of unmanned missions and the headquarters of the FSAT program are at Tyndall.

 Flying an airplane by remote control, in the USAF FSAT program, is very much like flying an aircraft simulator on a home PC. The controller sits at a console with one or two computer monitors (CRTs), an array of switches and push buttons, and a keyboard. Of course there is also a "joystick" used to "fly" with. The buttons, switches, and keyboard are used to issue commands for things like raising and lowering landing gear, for initiating and canceling different flight modes, etc. The brain is a RISC6000 computer on the ground, a similar computer in the jet, and if everything is working properly, and according to the plan, the computers can takeoff, fly the target profile, and land the drone (a remotely controlled vehicle is commonly known as a "drone") with minimum human assistance. If the drone gets hit by a missile, and can no longer fly normally, the computer has problems-that's where the Drone Controller is needed. The human computer, although usually slower in acting, is programmed to handle anomalies. All possible malfunctions, and "real time" changes to plans, cannot be programmed into "Clyde" (the RISC6000). When damaged, a drone is flown at landing speeds at a safe altitude to insure controllability during landing. If it can be controlled, it is flown back to the home base and landed. If there are any difficulties which would preclude a completely safe recovery, the drone is destroyed by an onboard bomb.

Taking off and landing a 50,000 pound jet fighter by remote control sometimes doesn't go as planned. Some have gone berserk and go off the runway resulting in an impressive fire ball! Thus, we practice frequently. While practicing remote control skills, and for the majority of FSAT missions, there is no intent to fire missiles at the targets. In these cases a human pilot is actually in the aircraft cockpit. This duty is known as "safety pilot." As a safety pilot, I strap in and start the jet, and taxi to the takeoff position on the runway. I then turn on several switches in the cockpit which "give control" to the pilot at the computer console. I then "ride" and observe that the jet does as planned. IF the controller's skills aren't perfect, IF the aircraft's onboard systems malfunction, IF the myriad of ground hardware develop problems, or IF the ground or aircraft software isn't programmed correctly, I squeeze a button on the "stick" and have full control of the aircraft back. When the discrepancy is solved, I turn one switch back on, and the guy on the ground is flying the airplane again. Most times the safety pilot will take control at the end of a mission, and land the airplane himself, in the conventional way. As safety pilots in the FSAT program, we have to accomplish the same currency and proficiency requirements as active duty U.S. Air Force pilots.  Buzz
