Seti Corridor. National Highway 65, NH65 is a proposed national highway in Nepal, located in Sudurpashchim Province. The total length of the highway is  of which  has been opened.

Background
The project to construct a road from Khutiya to Dipayal as an expressway was inaugurated on 16 December 2015. The road was supposed to be  expressway. Delays by the contractor, controversies over the forest, disputes between the federal and provincial governments over the jurisdiction, and other reasons has left the project in limbo. On the other hand, the road project from Chainpur to Urai Bhanjyang (Nepal-China border) was separately established as North Seti Highway while the road project from Chainpur to Khakraula (Indo-Nepal border) was established as South Seti Highway. Later, South Seti became (NH62) and North Seti Highway merged with Khutiya–Dipayal Expressway and became NH65.

Bäumer Aero. Bäumer Aero GmbH was a German aircraft manufacturing company founded by and named after Paul Bäumer. It is noted for producing the Bäumer Sausewind monoplane sports aircraft.

History

Paul Bäumer and Harry von Bülow-Bothkamp, were successful fighter pilots in the first World War, and founded Bäumer Aero GmbH in Hamburg on the 7th of November 1922 for the purpose of the sale of aircraft, accessories for airports and airships.

Initially sales of aircraft were from Udet Flugzeugbau and Dietrich Flugzeugwerke.
The first aircraft model to be produced was the “Red Bird” motor glider in 1924.

In 1925 the company became generally known for their Bäumer Sausewind sports aircraft which was successful in the 1925 Round Germany Flight. A total of four copies of the successful Sausewind model were built.

This was followed by the Alsterkind and Puck models.

The design and construction team consisted of the young engineers Walter Günter, Walter Mertens and Werner Meyer-Cassel. Walter Günter's twin brother Siegfried joined in 1926.

On the 15th of July 1927, Paul Bäumer was instantly killed when the Rohrbach Ro IX he was demonstrating to a Turkish army commission crashed. After climbing to 5,000 meters, the plane entered a spin and he was unable to recover and hit the water of the Öresund, near Copenhagen. As he was prime driving force of the company, all development and planning work came to a standstill. It took nearly a year before the Sausewind IV was completed in May 1928. Another year elapsed before the new Libelle model was produced. The new model was not successful, with both examples crashing. The company was liquidated at the end of 1930.

Nancy Rothwell Building. The Nancy Rothwell Building is home to the School of Engineering at the University of Manchester. Previously known as the Manchester Engineering Campus Development (MECD) and the Engineering Building it took nine years to design and construct and was completed in 2021.

The building has over 76,000m² of floor space spread over seven floors making it the largest home for engineering and material science in the UK. It provides a workspace to over 8,000 students, academics and staff. As of 2024 it is one of the single largest construction projects undertaken by any tertiary education institution in the UK.

Design and construction
The Initial budget for the building was £300 million project in 2015 rising to more than £420 million on completion.

Design and construction of the building was a collaboration between Mecanoo and the Building Design Partnership (BDP) with engineering services provided by Arup. The main contractor was Balfour Beatty with Buro Happold as the environmental sustainability advisor. The building has a BREEAM excellent rating and a green roof.

The building was constructed during period of heavy investment in buildings by universities in the United Kingdom. Such investments in building infrastructure have been criticised as a race to the bottom, building frenzy and a gold rush by critics such as Jonathan Wolff and Fionn Stevenson.

Naming

The building was officially named after Nancy Rothwell in July 2024 to mark her retirement as Vice Chancellor of the university in 2024. It is one of the few buildings named after a woman on campus. A portrait of Nancy Rothwell by Carla van de Puttelaar is displayed on the first floor outside the main lecture theatre.

Previously the building had been known as the Engineering Building and the Manchester Engineering Campus Development (MECD).

Fay-Riddell equation. The Fay-Riddell equation is a fundamental relation in the fields of aerospace engineering and hypersonic flow, which provides a method to estimate the stagnation point heat transfer rate on a blunt body moving at hypersonic speeds in dissociated air. The heat flux for a spherical nose is computed according to quantities at the wall and the edge of an equilibrium boundary layer.where  is the Prandtl number,  is the Lewis number,  is the stagnation enthalpy at the boundary layer's edge,  is the wall enthalpy,  is the enthalpy of dissociation,  is the air density,  is the dynamic viscosity, and  is the velocity gradient at the stagnation point. According to Newtonian hypersonic flow theory, the velocity gradient should be:where  is the nose radius,  is the pressure at the edge, and  is the free stream pressure. The equation was developed by James Fay and Francis Riddell in the late 1950s. Their work addressed the critical need for accurate predictions of aerodynamic heating to protect spacecraft during re-entry, and is considered to be a pioneering work in the analysis of chemically reacting viscous flow.

Assumptions 
The Fay-Riddell equation is derived under several assumptions:

 Hypersonic Flow: The equation is applicable for flows where the Mach number is significantly greater than 5.
 Continuum Flow: It assumes the flow can be treated as a continuum, which is valid at higher altitudes with sufficient air density.
 Thermal and Chemical Equilibrium: The gas is assumed to be in thermal and chemical equilibrium, meaning the energy modes (translational, rotational, vibrational) and chemical reactions reach a steady state.
 Blunt Body Geometry: The equation is most accurate for blunt body geometries where the leading edge radius is large compared to the boundary layer thickness.

Extensions 
While the Fay-Riddell equation was derived for an equilibrium boundary layer, it is possible to extend the results to a chemically frozen boundary layer with either an equilibrium catalytic wall or a noncatalytic wall.

Applications 
The Fay-Riddell equation is widely used in the design and analysis of thermal protection systems for re-entry vehicles. It provides engineers with a crucial tool for estimating the severe aerodynamic heating conditions encountered during atmospheric entry and for designing appropriate thermal protection measures.

Air Inter Flight 2611. The crash of Tramoyes involving the Air Inter Flight 2611 occurred on , when a Vickers Viscount 708 operated by Air Inter, which was on a scheduled service from Lille to Nice via Lyon, crashed in the early afternoon in Tramoyes in the southwest of the Ain department, during its approach to Lyon-Bron Airport, located about 15 kilometers away. While being held for landing, it encountered a severe thunderstorm. A wing of the aircraft struck two trees, then the roof of a farmhouse, and finally the aircraft collided with a reinforced concrete electric pole and crashed into a field. Twelve people were killed instantly, and four were seriously injured, but only one survived, a five-year-old girl. In total, the accident caused 16 fatalities: 11 of the 12 passengers, all 4 crew members, and 1 person on the ground. The probable cause of the accident was the blinding of the crew caused by a severe lightning flash, causing them to lose control of the aircraft.

Background

Aircraft 
The aircraft involved was a Vickers Viscount 708 built by the British company Vickers-Armstrong in 1954 for Air France and acquired by Air Inter on 16 March 1962. It was equipped with four turboprop engines of the Dart 506 type. It had accumulated 12732 flight hours.

Crew 

In command was Captain Georges Valencia, born on 1 September 1925, had logged 7400 flight hours. He was responsible for navigation and engine control on this flight. His co-pilot was First Officer Guy Cleret-Langavant, born on 21 July 1930, had logged 5795 flight hours. He was the pilot-flying on this flight. The Chief Flight Attendant was Christiane Souleil, born on 22 May 1939. She was seriously injured in the accident and requested Francis Girard, the first person to arrive at the accident site, to inform Bron Airport. She died at the Édouard Herriot Hospital in Lyon. The other Flight Attendant was Liliane Perois, born on 31 October 1942.

Other Air Inter and Vickers Viscount accidents
The crash of Tramoyes was the first of three aircraft crashes experienced by Air Inter during its existence (1958–1997), all three occurring in circumstances quite similar to those of the crash of Noirétable on 27 October 1972 (a Vickers Viscount coming from Lyon-Bron and approaching Clermont-Ferrand crashed in the Forez at night and in a storm) and the Mount Sainte-Odile disaster on 20 January 1992 (an Airbus A320 from Lyon-Satolas and approaching Strasbourg crashed in cloudy weather at night, near Mont Sainte-Odile).

The British medium-haul Vickers Viscount, launched in 1948, experienced a very large number of accidents during its career. Of the 445 aircraft put into service, there were 150 accidents or serious incidents, 144 of which resulted in the loss of the aircraft (List of accidents and incidents involving the Vickers Viscount).
