The Lockheed Corporation designed the P-38 in response to a February 1937 specification from the United States Army Air Corps (USAAC). Circular Proposal X-608 was a set of aircraft performance goals authored by First Lieutenants Benjamin S. Kelsey and Gordon P. Saville for a twin-engined, high-altitude "interceptor" having "the tactical mission of interception and attack of hostile aircraft at ...
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. [1]
For most applications, the difference between the two definitions is insignificant – one international foot is exactly 0.999 998 of a US survey foot, for a difference of about 1 ⁄ 8 in (3 mm) per mile – but it affects the definition of the State Plane Coordinate Systems (SPCSs), which can stretch over hundreds of miles.
The Sukhoi Su-57 (Russian: Сухой Су-57; NATO reporting name: Felon) [5] [6] is a twin-engine stealth multirole fighter aircraft developed by Sukhoi. [7] It is the product of the PAK FA (Russian: ПАК ФА, prospective aeronautical complex of front-line aviation) programme, which was initiated in 1999 as a more modern and affordable alternative to the MFI (Mikoyan Project 1.44/1.42).
Its range would increase by 400 nautical miles (740 km; 460 mi) and although 95% of the parts would be common with the A330ceo, maintenance costs would be lower. New winglets , 3.7 metres wider and similar to those of the A350 XWB , still within ICAO category E airport requirements, along with new engine pylons, would improve aerodynamics by 4%.
Though the treaty had provided for one hundred miles by one hundred miles in the New Mexico Territory, the size of the territory was 3,328,302 acres (13,470 km 2; 5,200 sq mi) [16] —slightly more than half. This initial piece of land is represented in the design of the Navajo Nation's flag by a dark-brown rectangle.
Ozone in the ozone layer filters out sunlight wavelengths from about 200 nm UV rays to 315 nm, with ozone peak absorption at about 250 nm. [55] This ozone UV absorption is important to life, since it extends the absorption of UV by ordinary oxygen and nitrogen in air (which absorb all wavelengths < 200 nm) through the lower UV-C (200–280 nm ...
