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.

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. It will be flown to a lake near Phoenix and partially dismantled so it can be trucked to the Pima Museum.

Hawaii Mars was flown to the British Columbia Aviation Museum in Victoria, B.C., last August. (Covered in Airplane Geeks #813.) The 16-foot props were removed from Hawaii Mars and installed on Philippine Mars for its flight.

US Airlines Plane Narrowly Avoids Collision with UFO Near New York, Prompting Increased Scrutiny of Unidentified Aerial Phenomena and Aviation Safety Concerns

The U.S. government released information on 757 reported Unidentified Aerial Phenomena (UAP) cases between May 2023 and June 2024. One case involved a near miss between a commercial airline flight and a “cylindrical object” over the Atlantic Ocean. This occurred just off the coast of New York and was classed as a “possible flight safety issue.” The airline and time of the encounter have not been made public.

UAP sightings are investigated by the Pentagon’s All-Domain Anomaly Resolution Office (AARO). Of the 757 UAP reports worldwide that AARO analyzed nearly 300 were resolved. This often related to balloons, birds, drones, and even satellites. Other sightings remain unexplained.

Spirit Airlines Files for Bankruptcy; Lost $2.2 Billion in 5 Years

Spirit Airlines, Inc. announced that it has entered into a restructuring support agreement supported by a supermajority of Spirit’s loyalty and convertible bondholders on the terms of a comprehensive balance sheet restructuring. Spirit expects the restructuring to reduce the company’s debt and provide increased financial flexibility.

Spirit says it will continue operating normally throughout the Chapter 11 process. Customers can continue to book and fly without interruption and can use all tickets, credits, and loyalty points as normal. According to the Airline, employee wages and benefits will not be impacted. Vendors, aircraft lessors, and holders of secured aircraft indebtedness will continue to be paid.

NBAA Fact Checks Misleading Report on Business Aviation Sustainability

On November 7, 2024, the journal Communications Earth & Environment published a study titled Private aviation is making a growing contribution to climate change. The abstract says, in part:

“Commercial aviation’s contribution to climate change is growing, but the global role of private aviation is not well quantified. Here we calculate the sector’s CO2 emissions, using flight tracker data from the ADS-B Exchange platform for the period 2019 to 2023. Flight times for 25,993 private aircraft and 18,655,789 individual flights in 2019-2023 are linked to 72 aircraft models and their average fuel consumption. We find that private aviation contributed at least 15.6 Mt CO2 in direct emissions in 2023, or about 3.6 t CO2 per flight… Emissions increased by 46% between 2019-2023, with industry expectations of continued strong growth. Regulation is needed to address the sector’s growing climate impact.”

The National Business Aviation Association (NBAA) has challenged the report for “selectively using data, making statements based on faulty analysis and ignoring facts to produce a one-sided set of conclusions about sustainability and business aviation – an industry that is on pace to achieve net-zero carbon emissions by 2050.”

The Need for Presque Isle’s New Airport Terminal

The terminal project is for an airport with only one flight per day, which is Essential Air Service (EAS) only.
