  • A contrails study by GE Aviation and NASA, an F-15E Strike Eagle downs drones, Iberia’s new A321XLR in service, the Phillippine Mars moves to its final destination, an airliner and a UAP come close together, Spirit Airlines files for bankruptcy, and the environmental impact of private jets. Also, AvGeeks flock to Bluesky, a STEM author at the NASM, and F-35B trials on a Japanese flattop. The contrails of an Airbus A340 jet, over London, England. Photographed by Adrian Pingstone in March 2007. Aviation News GE and NASA to accelerate understanding of contrails The "Contrail Optical Depth Experiment" (CODEX) is a research project conducted through a NASA and GE Aerospace partnership to study the formation and behavior of contrails. Contrails are clouds of ice particles that airplanes can create when they fly through cold and humid air. Persistent contrails are thought to contribute to climate warming. The primary goal of CODEX is to accurately measure the optical depth of contrails, which indicates how much light is blocked by the contrail. In the project, a GE Boeing 747-400 creates the contrails and NASA's G-III research aircraft (a modified Gulfstream III business jet) follows and scans the 747’s wake with Advanced LiDAR (Light Detection and Ranging) technology to analyze the contrails produced by different engine configurations. This will hopefully lead to the development of engine technologies that reduce contrail formation. NASA Gulfstream G-III NASA’s Armstrong Flight Research Center in Edwards, California, operates the Gulfstream G-III aircraft, NASA tail number 804, as an aerodynamics research test bed. Work with the aircraft is funded through NASA’s Aeronautics Research Mission Directorate (ARMD) as part of the Environmentally Responsible Aviation (ERA) project under the agency’s Integrated Systems Research Program. GE 747-400 Flying Test Bed Since 2010, this former Japan Airlines plane has been used by GE to test new jet engines, such as the GE90, GEnx, LEAP, and the GE9X. The plane is based at Flight Test Operations (FTO) in Victorville. F-15E Pilot Recounts Having To Switch To Guns After Missiles Ran Dry During Iranian Drone Barrage An F-15E Strike Eagle shot down so many Iranian drones aimed at Israel that they ran out of air-to-air missiles. The crew was ordered to continue and use any weapon available, which left the Strike Eagle’s 20mm Gatling Gun, capable of firing around 6,000 rounds per minute. Operating this gun is said to be risky with small, low, slow-moving targets. In this instance, the F-15 did not stop the drone. Feel Sorry For the Flight Attendants: Iberia’s New A321XLR Long-Haul Jet Features Tiny Galleys That Even Contortionists Would Struggle to Work in Iberia is the launch customer of the Airbus A321XLR (extra long range) single-aisle jet. The airline is flying the plane on a Madrid and Boston route. According to Saffran, the Airbus SpaceFlex V2 galley and lavatory allows for 6 more seats in the A321. The Airbus Space-Flex galley and lavatory concept. Airbus says the A321XLR features a 4,700 nm range, 180-220 seats, and 30% lower fuel burn per seat than previous generation aircraft. The plane was launched in 2019 at the Paris Air Show. Compared to other A320 family aircraft, the A321XLR carries more fuel, has strengthened landing gear, and includes a revised wing trailing-edge flap for takeoff performance. Airbus offers two engine options: the CFM LEAP-1A and the Pratt & Whitney PW1100G. The first A321XLR was delivered to Iberia on 30 October 2024 and conducted its first revenue flight on 6 November 2024. The first long-haul flight with passengers was on 14 November 2024, from Madrid to Boston. Martin Mars To Visit San Francisco, San Diego On Final Flight The Philippine Mars is destined for the Pima Air and Space Museum in Tucson, Arizona. In preparation, the plane is undergoing taxi tests in Port Alberni, British Columbia.
