The Disappearance Mystery of Flying Tiger Line Flight 739 On March 16, 1962, Flying Tiger Line Flight 739, a Lockheed L-1049H Super Constellation, vanished over the western Pacific Ocean. Chartered by the United States Army, the aircraft was transporting ninety-six military passengers from Travis Air Force Base in California to Saigon, South Vietnam, with planned stopovers in Honolulu, Wake Island, Guam, and Clark Air Base in the Philippines. The flight crew consisted of eleven American civilians. The aircraft, five years old with 17,224 airframe hours, departed Guam at 12:57 GMT after refueling and minor maintenance. At 14:22 GMT, Captain Gregory P. Thomas transmitted a routine position report. Approximately eighty minutes into the flight, communication with the aircraft ceased amidst heavy radio static from the Guam station. The disappearance triggered one of the largest air and sea searches in Pacific history, covering over 200,000 square miles. Despite the involvement of U.S. Navy, Air Force, Coast Guard, and Marine resources, no wreckage was recovered. A civilian tanker, SS T L Linzen, reported observing an in-flight explosion in the vicinity of the last known coordinates, along with two falling red lights, suggesting a mid-air break-up. The Civil Aeronautics Board (CAB) concluded that the aircraft likely exploded in-flight based on these observations, though the exact cause remains undetermined due to the absence of physical evidence. The possibility of sabotage was speculated, as another Flying Tiger Line aircraft carrying secret military cargo also met with disaster on the same day. Flight 739 carried 93 Army communications specialists and three South Vietnamese military personnel, all en route to assist in the Vietnam conflict. The catastrophic loss, presumed to have resulted in 107 fatalities, marked the deadliest single-aircraft incident involving the Super Constellation. Without concrete wreckage, the CAB's final report could not definitively pinpoint the cause, stating, "A summation of all relevant factors tends to indicate that the aircraft was destroyed in flight. However, due to the lack of any substantiating evidence, the Board is unable to state with any degree of certainty the exact fate of N 6921C."

MISSING MILITARY HELICOPTER FOUND AFTER SEARCH. Next generation warfare and defence is likely to be the things we can't see. With the advancements in and increased use of Unmanned technology, rapid deployment and vast space COMMUNICATIONS,SIGNALLING AND TRACKING will play key roles. However, even in todays world these are still critical areas for innovation and improvement. #defence #innovation https://lnkd.in/eycU-UHK

#tomcattuesday An F-14 of VF-103 "Sluggers" is taxied out of the landing zone and directed to Cat 1 for launch during "CQ" or carrier qualifications in 1994 onboard CVN-65. USS Enterprise had just finished a two-year overhaul that took four years and was back operating again, many of the crew for the first time, myself included, as a Catapult and Arresting Gear Officer. Depending on how many aircraft were CQ'ing, the initial launch would be from all four catapults and once the waist catapults were finished, they'd be buttoned up and there would be a "green deck" just as the planes were lined up to trap onboard. It was very hectic. Then, the forward bow catapults would only be used launching and trapping, until everyone was finished. If you look above the vertical stab, that rectangle is the jet blast deflector for Cat 2, and the top left panel had about 9 inches that "fouled" the entire landing zone if it was raised, which took even more coordination. Somedays it was amazing it all worked! The HAM F-14 is available to see every day, no admission charge to visit us. #f14 #tomcat #grumman #f14tomcat #jet #jets #airplane #airplanes #aircraft #aviation #aviationdaily #aviationlovers #aviationgeek #aviationgeeks #avgeek #avgeeks #avnerd #aviationphoto Friends of Naval Aviation, Inc. #aviationphotos #aviationphotography #flynavy #usnavy #navalaviation #tailhook #topgun #hickoryaviationmuseum #aviationmuseum

Aerial refueling, a vital technique for military and civil aviation, allows aircraft to remain in flight for extended periods, increasing their range and efficiency. During this process, a tanker aircraft transfers fuel to another aircraft in mid-flight, which is essential in combat, patrol and transport missions. There are two main methods of aerial refueling: the hose and basket system and the refueling point system. The first involves a hose connected to the refueling aircraft, which extends to a basket on the receiving aircraft, allowing the fuel to flow. The second method uses a rigid tip that connects directly to the aircraft, facilitating faster refueling. Historically, in-flight refueling began to be developed in the 1920s, and has since evolved with the improvement of aeronautical technologies. Aircraft such as the Boeing KC-135 Stratotanker and the Airbus A330 MRTT are examples of modern tanks used by various air forces around the world. This practice not only optimizes military operations, but is also employed in search and rescue missions and transport in remote regions. Aerial refueling ensures that aircraft can carry out their missions more effectively, avoiding interruptions and increasing the safety of operations. #aviation #aviationlovers #aviationdaily #Avgeek Credits: ig/ @allthingsexplained_

After Deadly Osprey Crashes, New 'Leading Theory' Points to Sprag Clutch Issues - Military officials now believe the root cause of deadly MV-22 Osprey incidents may be linked to "out of phase engagement" of the aircraft's sprag clutches. - The Osprey's complex drive system uses sprag clutches to address engine failure, but if the clutches engage unevenly, it can lead to a "hard clutch engagement" that can cause the system to fail catastrophically.? - This new "leading theory" comes after over a dozen HCE incidents, including a 2022 crash that killed 5 Marines. Previous fixes focused on replacing clutch components after a certain number of flight hours. - Officials say ongoing testing and analysis may lead to a better understanding of the root cause and a more effective solution to prevent future Osprey accidents. #MarineCorps #Navy #AirForce #Osprey #AircraftSafety #MilitaryTechnology #AircraftDesign #EngineeringSafety

???Step inside MQ-9 Reaper's ground control station for a closer look at Guardian, defense aviation's new detect-and-avoid system making crewed/uncrewed teaming safer developed by engineers at #NAWCAD. ???How does it work? Guardian tracks manned and unmanned systems across an airspace within a 200 nautical mile radius. The system improves airspace safety using ground-based sensors to communicate with air vehicle operators in ground control stations to provide visual cues for navigation and traffic avoidance maneuvers like turn, ascend, or descend in instances where collisions are imminent–all on a computer screen, similar to GPS in a car. ??Guardian earned Naval Air Systems Command (NAVAIR) certification last summer, and we're already using the tech successfully across our #NavalTestWingAtlantic and at U.S. Army Redstone Test Center (RTC). ??Looking ahead, we're eyeing Federal Aviation Administration certification so Guardian can operate across national airspace, and aiming to make Guardian a part of shipboard operations for a safer air wing of the future. #IAmNavalAviation #MakeAnImpact #NavyInnovation

What can be learned here?This is a great example of poor #strategicplanning. However, dire this cancelation appears, there seems to be sound logic and rational for the decision. In the end, this saves billions for tax payers. As painful as this decision seems, it's reassuring to know we've learned something from the Ukraine conflict. In the training and emergency services world's we spend hours, days, weeks, and months training for a purpose. Sometimes, when the moment we've trained for arrives, we find ourselves headed towards a head on with a train if our plan remains ridged to change. I've been involved with situations like this where parts of the #leadership structure are bedamned to #change course due to the time and effort engaged to plan. So it's appropriate to ask, and know if an #organization or its leadership can be rigidly nimble for change to avert disaster?
Vertical Flight Society Director of Strategy Mike Hirschberg is a contributor to Forbes.com. Here's his perspective on last month's cancellation of the Future Attack Reconnaissance Aircraft (FARA) program by the US Army. "Like a bad version of the 'Groundhog Day' movie, this unexpected termination capped five different attempts to field an armed scout replacement for the Vietnam War-era OH-58 over the past half-century." https://lnkd.in/eqexe9YU #helicopter #rotorcraft #ArmyAviation #FARA #FVL #FutureVerticalLift #Aviation #avgeek Bell Flight Sikorsky PEO Aviation U.S. Army DEVCOM Aviation & Missile Center
