The Elizabeth line is an underground railway line operating east to west through London and its surrounding areas. It connects stations in the western part of London, such as Reading Station and Heathrow Airport terminals, with Abbey Wood Station or Shenfield Station in the east. Originally consisting of only the Great Western Main Line and the Great Eastern Main Line, a new section was constructed in central London to directly connect these lines as part of the “Crossrail” project. After the opening of this new section, the line was renamed the “Elizabeth line” as a collective name. This report details the findings from an inspection of the line that the author conducted. < Back Surface Transportation August 2025 Inspection Report on the London Underground Elizabeth Line By Haruhiko Koyama The Elizabeth line is an underground railway line operating east to west through London and its surrounding areas.

In fiscal year 2025, significant progress was made toward the social implementation of Advanced Air Mobility (AAM) in Japan. Demonstration flights of multiple types of AAM aircraft were conducted at the Expo 2025 Osaka, Kansai, allowing many visitors to gain an understanding of the current state of the technology and significantly raising public awareness of AAM. Furthermore, in March 2026, the Public-Private Committee for Advanced Air Mobility revised the “Advanced Air Mobility Roadmap” and the “Concept of Operations for Advanced Air Mobility,” outlining a more detailed plan for AAM leading up to the 2040s. This marked a major policy advancement, including the decision to use the term “空飛ぶクルマ (AAM)” instead of simply “空飛ぶクルマ” (a direct English translation being flying car), with the internationally recognized AAM acronym included in the new terminology. Meanwhile, in the United States, major announcements regarding AAM were made between late 2025 and early 2026. In December 2025, the U.S. Department of Transportation released the Advanced Air Mobility National Strategy 2025, a national blueprint for AAM through 2036, and the accompanying Advanced Air Mobility Comprehensive Plan 2025 outlined a vision and action plan for the societal implementation of AAM for the same timeframe. In addition, in March 2026, the Federal Aviation Administration announced that it had selected the first eight proposals for the Electric Vertical Takeoff and Landing Integration Pilot Program based on the June 6, 2025, Executive Order UNLEASHING AMERICAN DRONE DOMINANCE. Going forward, these developments are expected to further advance U.S. policies aimed at the social implementation of AAM. This report provides an overview of the Advanced Air Mobility National Strategy 2025, which serves as a core framework for the U.S. government’s AAM policies. < Back Civil Aviation May 2026 U.S. Trends in AAM Policy and Related Developments ~Advanced Air Mobility National Strategy 2025 ~ By Kotaro Yamamoto In fiscal year 2025, significant progress was made toward the social implementation of Advanced Air Mobility (AAM) in Japan.

After the end of the Concorde's flight operations in 2003, and the existing problems of fuel inefficiency and noise complaints, supersonic flight for commercial aircraft seemed like a pipe dream. However, with new technology and the start of several recent development projects, the possibility of their return has increased. This new excitement, too, has meant that existing standards and procedures have needed a relook, which is discussed in this report. < Back Civil Aviation Review of Special Flight Authorization Procedures for Civil Supersonic Aircraft and Developmental Trends of New Noise Standards By Yoshihiro Fujimaki After the end of the Concorde's flight operations in 2003, and the existing problems of fuel inefficiency and noise complaints, supersonic flight for commercial aircraft seemed like a pipe dream.
