The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts.
 The Mustang was designed in 1940 by North American Aviation (NAA) in response to a requirement of the British Purchasing Commission.
 The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF).
 Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter.
 The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October.
The North American Datum (NAD) is the datum now used to define the geodetic network in North America.
 A datum is a formal description of the shape of the Earth along with an "anchor" point for the coordinate system.
 In surveying, cartography, and land-use planning, two North American Datums are in use: the North American Datum of 1927 (NAD 27) and the North American Datum of 1983 (NAD 83).
 Both are geodetic reference systems based on slightly different assumptions and measurements.
Abies lasiocarpa, commonly called the subalpine fir or Rocky Mountain fir, is a western North American fir tree.
Abies magnifica, the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States.
 It is a high elevation tree, typically occurring at 1400 - elevation, though only rarely reaching tree line.
 The name red fir derives from the bark color of old trees.
Tuber oregonense, commonly known as the Oregon white truffle, is a species of edible truffle in the genus "Tuber".
 Described as new to science in 2010, the North American species is found on the western coast of the United States, from northern California to southern British Columbia west of the Cascade Range.
 A mycorrhizal fungus, it grows in a symbiotic association with Douglas fir.
 It overlaps in distribution with the closely related "T. gibbosum", but they have different growing seasons: "T. oregonense" typically appears from October through March, while "T. gibbosum" grows from January to June.
 The fruit bodies of the fungus are roughly spherical to irregular in shape, and resemble small potatoes up to 5 cm in diameter.
 Inside the truffle is the gleba, which is initially white before it becomes a marbled tan color.
 The large, often thick-walled, and strongly ornamented spores are produced in large spherical asci.
 The truffle is highly prized for its taste and aroma.
 Some individuals have claimed success in cultivating the truffles in Christmas tree farms.
Abies procera, the noble fir, also called red fir and Christmastree, is a western North American fir, native to the Cascade Range and Coast Range mountains of extreme northwest California and western Oregon and Washington in the United States.
 It is a high altitude tree, typically occurring at 300 - altitude, only rarely reaching tree line.
Canada balsam, also called Canada turpentine or balsam of fir, is a turpentine made from the resin of the balsam fir tree ("Abies balsamea") of boreal North America.
 The resin, dissolved in essential oils, is a viscous, sticky, colourless or yellowish liquid that turns to a transparent yellowish mass when the essential oils have been allowed to evaporate.
Abies balsamea or balsam fir is a North American fir, native to most of eastern and central Canada (Newfoundland west to central British Columbia) and the northeastern United States (Minnesota east to Maine, and south in the Appalachian Mountains to West Virginia).
The North American Sabreliner, later sold as the Rockwell Sabreliner, is an American mid-sized business jet developed by North American Aviation.
 It was offered to the United States Air Force (USAF) in response to its Utility Trainer Experimental (UTX) program.
 It was named "Sabreliner" due to the similarity of the wing and tail to North American's F-86 Sabre jet fighter.
 Military variants, designated T-39 Sabreliner, were used by the USAF, United States Navy (USN) and United States Marine Corps (USMC) after the USAF placed an initial order in 1959.
 The Sabreliner was also developed into a commercial variant.
Phaeocryptopus gaeumannii or Swiss needle cast is a fungus that infects Douglas fir and causes yellowing of foliage and reduction in growth.
 It is endemic in western North American stands of Douglas fir, but was first discovered in trees planted Switzerland.
