Details of the Predator UAV crash in Arizona have just been released.
Currently two of these pilotless 66-foot wing-span beasts are flying along the Arizona border as part of border patrols and a third will be added next year. Some of us local pilots are underwhelmed. The crash resulted from loss of control after the ground computer- control console locked up. Reportedly, two identical consoles are used, one for the aircraft controls and one for the surveillance equipment. The control for the throttle on one console is identical to the control for the camera iris on the other. After the main console locked up, the pilot switched control from one console to the other without checking that the controls were matched. Since the iris was closed, the throttle shut down and the engine quit. The Predator then descended below the minimum altitude for the C-band communications link, which was lost. The aircraft then turned north into Arizona and waited for further commands. Backup commands can also be sent by Iridium satellite. Unfortunately, on loss of engine power, the Predator begins shutting down electrical systems to conserve power. And yes indeed, the Iridium communications is one of the first to be shut down! The out-of-control and powerless Predator then glided into an area of upscale ranch homes near Tubac, about 12 miles north of the Arizona/ Mexico border, where it crashed in the backyard of a large house, missing it and a neighbor by just a few hundred feet.(The FAA report claims it crashed in sparsely populated terrain, but failed to mention that it just missed a group of houses). During its descent, ATC closed off large chunks of airspace below 15,000 feet as they didn't know where the lost aircraft was or its heading. From primary radar returns, at one point it was considered possible that it would affect Tucson International airspace. The Predator controls appear to violate a lot of good design principles - in particular, that the intelligence should be in the machine, not the operator. I can see how a tired operator at 3:00 AM can easily hit the wrong button when the design makes it so easy. Losses of these in active war zones from equipment malfunctions and pilot errors are unsurprisingly quite a lot higher. It may also come as no surprise that these aircraft have no airworthiness certificate and are being flown under a special waiver "in the national interest". Why is this posted on a glider forum? Arizona has a lot of military airspace and they are trying to grab more. To operate the Predators and similar flying disasters, more airspace is being commandeered, a big chunk of it in some of our best soaring country. The Predator crashed about five miles from one of most used southern-Arizona turnpoints. In my view, too much money is being spent on technical solutions to a political problem and I am particularly concerned about the further grabbing of airspace for this ineffective and horrendously expensive form of border patrol.

Wow, that's an eye opener. A bunch of contractors are swapping
processor cards, rebooting computers, power-cycling whole racks of gear, and calling on their cell phones for backup. You'd think that Yahoo or google.com had come up with a 404 or the like. Except: The Predator B is approximately 36 feet in length with a wingspan of 66 feet. The maximum gross weight is 10,000 pounds... ...The aircraft total fuel capacity was 3,920 pounds... When eBay goes down, it doesn't land in folks' back yards. When it's up, it doesn't consume vast blocks of airspace. And when you pull the plug it definitely sinks at less than 1 fps. Bob K. |

Thankyou, Mr Strike, for the shortened view, the actual report is indeed heavy going!
Again we see USAF big brother at his not-responsible best. Fortunately it wasnt an Italian chair lift this time. The fact that the operators are referred to as "Pilots" is alarming enough. When I dive my kids toy sub through her bathtub remotely, am I now a sub-mariner? Apparently so! Dont be assuming these things are just looking at border patrols, either, they are being used to shoot at people in war theatre around the globe, very effectively. One can only put 2 and 2 together to figure that if a UAV was met in the air by a glider that its natural programming will (if not now, soon enough) have the UAV shoot us out of the sky. Jump up and down, write letters, complain. Thanks again, Mr Strike, if I look back on all the scare mongering about the Soviet Union fed to us over the last 40 years, this kind of thing appears alarmingly similar. Or is it the Terminator movies? More sleepless nights. Bagmaker |

Arizona is not theonly UAV program. see
Submarine Force Tests UAV Technology to Enhance Force Protection Story Number: NNS050331-02 Release Date: 3/31/2005 2:00:00 PM By Journalist 2nd Class Christina M. Shaw, Commander, Submarine Force, U.S. Atlantic Fleet Public Affairs KINGS BAY, Ga. (NNS) -- The submarine force conducted a demonstration here in February using a new type of Unmanned Aerial Vehicle (UAV) to test its utility for force protection. During the demonstration, a prototype UAV was launched and controlled by force protection personnel ashore to search out the waters ahead of the submarine as it entered port. The small plane weighing in at approximately five pounds is able to break down into five pieces and can be stored in a small suitcase, making it portable and easy to take anywhere it's needed. "The beauty of UAVs as other military users have found is they are economical, portable and reliable," said Lt. Cmdr. Tom Armstrong, Commander, U.S. Naval Submarine Force anti-terrorism force protection officer. The UAV can be used in a number of different ways, but its primary purpose for the submarine force would be for reconnaissance and photographic surveillance to support force protection. The new UAV design is ideal for stealth, due to its ultra-quiet electric motor and small size. Another plus comes in the versatility of the vehicle. According to Armstrong, it can be flown in all kinds of weather and can be launched in a very unique way. "It can be flown via Global Positioning System (GPS). We just program what route we want it to fly and it doesn't matter if it's night or day, in bad weather or good," he said. "We could launch the UAV from the submarine at sea or launch it from shore depending upon the available range." Acquisition of this UAV for submarine force protection is still under consideration, but Armstrong is optimistic this technology will be a part of the fleet in the future. "This affordable surveillance tool offers great potential benefits and savings to the submarine force, and I hope we'll be able to take advantage of this great technology soon." For related news, visit the Commander, Submarine Force U.S. Atlantic Fleet Navy NewsStand page at www.news.navy.mil/local/sublant. Great new for those of us who fly down the coast. A GPS controled blind bird Great. But don't worry our FAA is protecting us. right? Has anyone crossposted to rec.aviation.piloting?

Mike You guys are conveniently ignoring, because I know that you know better, that piloted military a/c have also crashed, including at largely attended public events such as airshows. And in the USA. The pilot did not follow procedures and failed to even look at the check list. How is this different from a manned a/c crash where the same sequence of events occurred? I am, however, very sympathetic to any loss of airspace. Join the AOPA and fight it, but it isn't a UAV only issue. That is far more effective than a rant on RAS. Tom |

![]() pilot did not follow procedures and failed to even look at the check list. How is this different from a manned a/c crash where the same sequence of events occurred? Because it had no airworthiness certificate - we don't let real people (even the more expendable military) fly in those. If the airworthiness couldn't be guaranteed, we wouldn't normally let an aircraft fly. Following procedures can only go so far. Robust designs minimize the chance of a mishap. It should be obvious that if you have two identical buttons, one which snaps a photo and the other that releases a missile, that the system might ask "are you sure" before implementing it. The current design is not robust has no margin for error. The loss of 100% of the operational UAVs in the Arizona sector in 2006 should be testimony to something! I have no problem with real pilots doing this job if it's necessary. I know some who do and it is apparently very effective. UAVs are a costly boondoggle that provide little border security while gobbling up money, resources and our airspace. If we really wanted to protect the border, we'd stick up a big fence and scatter some land mines around it. Mike PS UAVs are coming to the Canadian border too! |

They are the future of aircraft. Unless you know how they operate and are controlled don't jump to scary and poorly reported events. I know a lot of Predator pilots. Many are flown by glider pilots. They can read an N number 25 miles away. Have any live piloted aircraft crashed...into homes and killed people on the ground? Has your computer ever crashed? Things break. If you have political objections, say so. I want our country protected from another 9-11 and being absorbed by illegal and dangerous people. Fence yes, Cameras yes, overseas calls monitored, yes. I am a proud American, I believe in the bible. So there! Fred Robinson |

You want scary and poorly reported - here's another one for
you........ "The crash of a remote-controlled MQ-1 Predator on Aug. 3 at Creech Air Force Base, Nev., resulted from a civilian contract pilot pushing the wrong button, an Air Force accident investigation board concluded in a report issued Thursday. The aircraft was assigned the Predator formal training unit, the 11th Reconnaissance Squadron at Creech. As the aircraft flew near the base at an altitude of about 500 feet, the pilot pressed the button he thought would retract the airplane's landing gear. Instead, the button shut down the engine. The pilot couldn't restart the motor. He tried to steer the powerless plane to a runway, but the propeller-driven plane crashed. The total cost of the damage was pegged at $1.4 million." Pushing the wrong button seems to be a bit of a problem with this particular aircraft control system. Maybe that's why over 25% of Predators in the Iraq and Afghan theaters are lost to pilot error? That's about double the rate for enemy fire. Mike PS: I'm all for keeping dangerous folks out of the USA. I just think they are more likely to legally fly in from Saudi Arabia on a scheduled airline flight like the last lot did. Most Mexicans walking into Arizona just want to pick fruit, milk cows or mow lawns. And I haven't noticed any spectacular decrease in their numbers since the UAVs were deployed. |
