Great shot of the Thunderbird F-16 Ejection
Over on "alt.binaries.pictures.aviation" someone has posted a terrific, high
resolution, nearly head-on shot of the Air Force Thunderbird F-16 ejection sequence from the crash in Idaho a few months ago. It REALLY shows how close the pilot came to hitting the deck before ejecting. It turns out the pilot didn't convert his altitude from MSL to AGL correctly, and thus started the split-S maneuver some 800 feet too low. For those interested in the accident report, here it is: ************************************************** *********** Thunderbird accident report released [Updated] Wednesday, January 21, 2004 - 09:10 PM A pilot's error caused a Thunderbirds F-16C to crash shortly after takeoff during a September airshow at Mountain Home Air Force Base, Idaho. The pilot ejected just before the aircraft impacted the ground. On Wednesday, the Air Force Accident Investigation Board held a news conference at the home of the Thunderbirds - Nellis Air Force Base - to announce what caused an F-16 to crash last September. According to the accident investigation board report the pilot, 31-year-old Captain Chris Stricklin, misinterpreted the altitude required to complete the "Split S" maneuver. He made his calculation based on an incorrect mean-sea-level altitude of the airfield. The pilot incorrectly climbed to 1,670 feet above ground level instead of 2,500 feet before initiating the pull down to the Split S maneuver. When he realized something was wrong, the pilot put maximum back stick pressure and rolled slightly left to ensure the aircraft would impact away from the crowd should he have to eject. He ejected when the aircraft was 140 feet above ground - just 0.8 seconds prior to impact. He sustained only minor injuries from the ejection. There was no other damage to military or civilian property. The aircraft, valued at about $20.4 million, was destroyed. The difference in altitudes at Nellis and Mountain Home may have contributed to the pilot's error. The airfield at Nellis is at 2,000 feet whereas the one at Mountain Home is at 3,000 feet. It appears that the pilot reverted back to his Nellis habit pattern for s aplit second. Thunderbird commander Lt. Col. Richard McSpadden said Stricklin had performed the stunt around 200 times, at different altitudes during his year as a Thunderbird pilot. McSpadden says Stricklin is an exceptional officer. "He is an extremely talented pilot. He came in here and made an honest mistake," says Lt. Col. McSpadden. But that mistake has cost Stricklin his prestigious spot on the Thunderbird team. "He's assigned to Washington D.C.," says McSpadden. "He's working in the Pentagon there in one of the agencies." The maneuver the pilot was trying to complete is called the "Split S Maneuver." The stunt requires that the pilot climb to 2,500 feet. Investigators say Stricklin only climbed to 1,670 feet before he went into the spinning roll. The board determined other factors substantially contributed to creating the opportunity for the error including the requirement to convert sea level altitude information from the F-16 instruments - to their altitude above ground and call out that information to a safety operator below. But the Air Force has now changed that as a result of the crash. Thunderbird pilots will now call out the MSL (mean-sea-level) altitudes as opposed to the AGL (above-ground-level) altitudes. Thunderbird pilots will now also climb an extra 1000 feet before performing the Split S Maneuver to prevent another mistake like the one on Sep.14, 2003 from happening again. Captain Chris Stricklin has been in the Air Force since 1994 and flew with the Thunderbirds since their first season. He has logged a total of 15,000+ flight hours and has received numerous awards. He served as a flight examiner, flight instructor and flight commander. The Thunderbirds will again take to the skies this year. They have 65 air shows scheduled. The September crash was the second involving a Thunderbirds jet since the team began using F-16s in 1983. Pilot error was blamed for a Feb. 14, 1994, training crash involving in a maneuver called a spiral descent at the Indian Springs Auxiliary Airfield, northwest of Las Vegas. The pilot survived, but the maneuver was discontinued. The worst crash in Thunderbird history, dubbed the "Diamond Crash," came when four pilots crashed Jan. 18, 1982, during training at Indian Springs. A malfunction in the lead plane was blamed. ************************************************** *********** -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

Although this photo may be genuine, the first thing that I asked myself was "where was the photographer standing and why he hadn't dropped his camera and run?" Captain Chris Stricklin has been in the Air Force since 1994 and flew with the Thunderbirds since their first season. Hardly....The Thunderbirds have been around long before 1994. Perhaps they meant to say "since the first of THIS season. He has logged a total of 15,000+ flight hours I find that REAL hard to believe. Bob Moore |

Ok, somebody smarter than me tell me why they wouldn't set their altimeter's to 0 before take off to prevent something like that. I'm with you....that way every show would be exactly the same. Bob Moore |

... Ok, somebody smarter than me tell me why they wouldn't set their altimeter's to 0 before take off to prevent something like that. Because KMUO is at 2996 feet, and Air Force planes' altimeters won't go down to 26.92? Much the same reason that we don't have the convenience of setting QFE around an airport, which is routine in flat old England. -- David Brooks |

If I remember correctly, he said that they fly 2 (or 3 ?) years with the T-Birds, no longer. The T-Birds have been flying since the mid 50's. First planes were F-84's Also, wasn't it about 1994 when they started flying again? Remember, they had a crash and they stopped flying for several years. |

because the MSL altitude of the ground is to high above sea level and it
can't be turned down that far to "zero".. we have the same problem with flat land sail plane pilots.. if I set my local altimeter to zero.. which I can't because it's to far to go.. beyond the adjustment range of the altimeter.. then how do I know I'm high enough to clear the local mountains.. or if my landing airport is still 2500ft above the airport I take off from.. I have to do the mental math calculation to know my AGL altitude. BT "Jim" wrote in message ...

Snip IIRC, Per the images I saw on the local TV station's website (which had been collected from air show patrons) the jet went down along a line near the base of the tower: http://www.borinquenrc.com/images/tb-crash/tb6-4.jpg I'd be willing to bet that there was a photographer working from the tower. Possibly either a team photographer or one for a vendor/supplier/civilian contractor. I think the angle of the photo looks right. Someone with a very big piece of glass (400-600mm owing to the amount of compression), and he/she nailed a once in a lifetime "Money Shot." Over on alt.binaries.pictures.aviation, one of the folks who posted the picture claims he got it in a very large size (3000+ x ???) from someone at Boeing. People have been imploring him to post the original. Boeing (until selling the operation to BF Goodrich) manufactured the ACES II seat used in the F16. http://www.boeing.com/news/releases/...se_991103n.htm Just my hunch... Jay In AZ |

isn't it amazing how a long telephoto lens can kill the depth perception and
make you think you are right there.. BT "Jay Honeck" wrote in message news:5igQb.131182$I06.1149412@attbi_s01...
