What to expect at EAA AirVenture Oshkosh 2026 and an interview with the Manager of Onsite Learning at the Smithsonian’s National Air & Space Museum. Also, how L3Harris converted the Qatari-gifted 747 into Air Force One, the Cirrus TRAC10, window seat lawsuits, a rule change to allow supersonic flight over the United States, and an update on Boom Supersonic’s strategy for its self-developed Symphony engine.

He has served in that capacity since 2010 and has been with the organization since 1992. Dick serves as the liaison between the media and EAA throughout the year, particularly during EAA AirVenture Oshkosh, the world’s largest fly-in convention. The event runs July 20-26, 2026. Dick Knapinski Boeing Plaza will be packed with aircraft to celebrate the aviation technology theme. Currently planned innovation displays for July 21 include BETA Technologies, Bye Aerospace, Jetson, American Drone, MagniX, Zipline, Embry-Riddle Aeronautical University, Airhart Aeronautics, Merlin Labs, Amazon Delivery, and Starlight Productions. In addition to the displays on Boeing Plaza, Bye Aerospace, Jetson, BETA Technologies, American Drone, and ScaleWings plan to fly during the afternoon air show. Drone delivery company Wing will display the latest developments in its operations at Twilight Flight Fest. Learn more about the AirVenture Airshows and performers, Aircraft Anniversaries & Gatherings, Authors Corner, AviationTech, KidVenture, and the Fly-In Theater. Rare warbird static/flying displays will include the B-29 “Doc,” as well as a rare Consolidated PB4Y and the CAF’s B-24 Liberator on static display at Boeing Plaza. Vicky Benzing will fly her P-51 “Plum Crazy,” and Bernie Vasquez will demo a Republic P-47 Thunderbolt in afternoon shows. The Aviation Gateway Park will spotlight helicopters, advanced vertical lift platforms, and eVTOL aircraft through static displays and interactive exhibits. Before joining EAA, Dick built a broadcasting career in Wisconsin, including stints as Program Director at WNBI Radio, News Director at WMGV Radio, and Station Manager at WLFM-FM/Wisconsin Public Radio. He also spent years as a sportswriter for the Appleton Post-Crescent. Dick holds a private pilot certificate and remains active as a writer and spokesperson for EAA. Aviation News How was the new Air Force One prepared for flight? The two permanent VC-25 replacements were selected in 2015, and the $3.9 billion fixed-price contract was signed in February 2018. Boeing began physical refurbishment work in February 2020 on two 747-8I airframes originally built for the bankrupt Russian carrier Transaero. Boeing has already reported $2.5 billion in losses on the program. The current delivery target for the first jet is between 2027 and 2028, with the second jet to follow later. The ex-Qatari 747-8 “bridge” aircraft was gifted to the U.S. Air Force in May 2025 and entered service on July 1, 2026. L3Harris did the conversion in about 10 months. The quick conversion was accomplished due to several factors: Pre-staged employees operated on a 24/7, three-shift structure. (Boeing has worked a normal single-shift industrial pace, with no incentive to surge, staff once costs started ballooning.) The bridge aircraft came with a luxury interior. (Boeing’s jets had incomplete interiors – basically shells.) Missing VC-25 elements. Reports (unconfirmed by the government) include no evidence of defensive countermeasures and a lack of EMP hardening. L3Harris didn’t out-engineer Boeing. They ran a 24/7 surge crew on a plane that already had a finished VIP interior, targeted a much narrower requirement (“executive airlift” vs. full presidential command-post survivability), and the government has not been forthcoming about which hardened-aircraft features (EMP shielding, missile countermeasures, full secure comms suite) were omitted.

Cirrus launches TRAC10, a new light aircraft for the flight training market Purpose-designed for flight schools and to be powered by a turbocharged Rotax 916 iSc FADEC engine, the plane has a three-seat interior, a Garmin flight deck, and the Cirrus Airframe Parachute System. Cirrus says they have 100 orders from 13 flight schools. United Airlines must face lawsuit over ‘window seats’ that lack windows Not every “window seat” has a window. Sometimes it has a wall. That’s just the way it is. But last August, some passengers filed class actions against United Airlines and Delta Air Lines, claiming that the carriers failed to properly disclose the lack of a window during the booking process. United claimed that “window seat” described the seat’s location and did not contractually promise that the seat would, in fact, have a window. In San Francisco, U.S. District Judge James Donato rejected the airlines’ request to dismiss the suit. New Rule Clears Way for Quiet Supersonic Flights By way of history: The FAA issued 14 CFR § 91.817 in April 1973, prohibiting civil aircraft from flying at speeds exceeding Mach 1 over land in the United States. The ban came as a result of early Air Force and NASA-controlled boom tests over cities, concerns over the Boeing 2707 SST program, and the impending arrival of the Concorde. NASA’s X-59 QueSST is flying specifically to gather community-response data on its “quiet boom” design. In a Notice of Proposed Rulemaking (Proposed rule: Enabling Supersonic Overland Flight), the FAA is looking to replace the blanket Mach-1 ban with a noise-based standard. Supersonic flight over land would be permitted if the boom signature falls under a certain loudness threshold. The NPRM states, “Manufacturers have demonstrated it is possible to fly supersonic aircraft without sonic booms reaching the surface by using sonic boom abatement techniques, making complete prohibition on civil supersonic flight outside of test areas no longer appropriate and an unnecessary restraint on the growth of the U.S. aviation sector.” The NPRM shifts the regulatory trigger from speed to noise. Right now, § 91.817 just bans anything faster than Mach 1 over land. The proposed rule keeps that structure but adds an exception: an operator may exceed Mach 1 if it can demonstrate that the sonic boom’s overpressure at the surface does not exceed 0.11 pounds per square foot (psf). This NPRM only covers en-route/overland boom noise. A separate rule on takeoff/landing noise is expected later this year, with both rules targeted for finalization by mid-2027. The comment period ends August 17, 2026, at 11:59 PM EDT. Boom Supersonic Q2 2026 Update https://youtu.be/gtf0-bVSbeA?is=GmG8VhICNm4wg7tP The FAA proposal to change from speed regulation to noise regulation is something Boom Supersonic and others have been seeking. In the Boom Supersonic Q2 2026 Update video, Blake Scholl reveals Boom’s strategy for the Symphony engine. The company intends to market a variant of the engine for behind-the-meter power generation that AI companies can utilize for power. In large part, the engine OEMs wouldn’t develop an engine for the Overture because the huge development cost couldn’t be covered by the expected engine volume. So when Boom announced it was developing its own engine, the business case was unclear. But by focusing on the ground power generation market, Boom can spread development costs over a greater number of engines. Also, that revenue stream would generate cash flow for the Overture program. National Air and Space Museum Celebrates 50 Years With Opening of Five New Galleries Hillel attended the Smithsonian’s National Air & Space Museum media preview of the opening of the five galleries. Last episode, we listened to two recordings from that event. This week Hillel speaks with Mike Hulslander, the museum’s Manager of Onsite Learning. Mike has worked in museums and zoos for more than 28 years and has researched, written, presented, and evaluated science programs for school groups, families, and the general public. At the Air and Space Museum, he is responsible for science-focused programs and exhibitions. Mike also manages the Museum’s learning centers: How Things Fly and the Design Hangar. Mike is also an adjunct faculty member at the National Center for Earth and Space Science Education. He serves as a science educator on the Student Spaceflight Experiments Program national review panel for experiment selection and has participated in reviews for the past 11 missions aboard the Space Shuttle and the International Space Station.
