UK fighter jets have intercepted two Russian aircraft off the Scottish coast, defence chiefs have said. The Ministry of Defence said the RAF Typhoons were scrambled after the Russian aircraft "entered the UK's controlled zone of international airspace". The Russian planes were identified as TU-142 Bear F maritime reconnaissance and anti-submarine warfare aircraft. The RAF aircraft are currently operating from Leuchars in Fife. An MoD spokesman said monitoring of the controlled zone ensured safe passage for other aircraft, including civilian transatlantic liners.
Berlin – The German government has said it has excluded Japanese-made P-1 patrol aircraft from its list of candidates for a patrol plane to be purchased by around 2025. Purchasing the P-1 would involve substantial temporal and legal risks as Germany lacks an adequate cooperative relationship with Japan, the government said in a written answer to a question from a lawmaker. In the past, Japan tried unsuccessfully to sell the P-1, used by the Maritime Self-Defense Force, to other countries including the United Kingdom. Currently, the German government is selecting a stopgap patrol plane to be used from 2025 to around 2035. The German military will retire its current P-3C aircraft, built by Lockheed Martin Corp. of the United States, in 2025. Its next-generation patrol plane, to be developed jointly by Germany and France, is scheduled to be introduced in around 2035.
The Oklahoma Highway Patrol says the crash occurred about 5:30 p.m. Saturday as the aircraft was approaching the Alva Municipal Airport. Troopers say a preliminary investigation indicates the aircraft experienced a mechanical failure during descent and that its landing gear struck some power lines. Authorities say the small aircraft struck some trees, plummeted to the ground and burst into flames.

For aircraft manufacturers, the market demand in the nowadays aeronautical industry requires a high reactivity between teams in charge of the design of the aircraft and teams in charge of its production system. One way to increase this reactivity is to help the design architects understand the way the aircraft is produced together with the bottlenecks in the manufacturing process, and to help them evaluate the impact of a design modification on the production system. This paper addresses these two needs. We formally describe the scheduling problem considered, the algorithmic approaches developed, the implemented tool, and results obtained on data from a real production line of the Airbus A320 aircraft family.
