Long observation has taught Mason that most landscape can be reduced to three essential planes: a foreground in sharp focus -- either a light area with dark accents or a dark one with lights ; ;

In November 2006 Libya supplied Chad with four Aermacchi SF. 260W light attack planes.

While light, highly maneuverable aircraft did have some advantages in fighter-versus-fighter combat, those could usually be overcome by sound tactical doctrine, and the design approach of the Italians and Japanese made their planes ill-suited as interceptors or attack aircraft.

Other problems with Japan's fighter aircraft also became apparent as the war progressed, such as their lack of armor and light armament, which made them inadequate as bomber interceptors or ground-attack planes — roles Allied fighters excelled at.

While the nonrestorative methods can improve contrast by removing out-of-focus light from focal planes, only the restorative methods can actually reassign light to its proper place of origin.

* 1943 – World War II – Battle of Berlin: 440 Royal Air Force planes bomb Berlin causing only light damage and killing 131.

* November 18 – WWII: The Royal Air Force opens its bombing campaign against Berlin, with 440 planes causing only light damage and killing 131.

Diamonds in general, including the Hope Diamond, are considered to be the hardest natural mineral on the Earth, but because of diamond's crystalline structure, there are weak planes in the bonds which permit jewelers to slice a diamond and, in so doing, to cause it to sparkle by refracting light in different ways.

Where the distance between the regularly packed planes of spheres is approximately half the wavelength of a component of visible light, the light of that wavelength may be subject to diffraction from the grating created by the stacked planes.

The spacing between the planes and the orientation of planes with respect to the incident light determines the colors observed.

The out-of-focus light is suppressed: most of the returning light is blocked by the pinhole, which results in sharper images than those from conventional fluorescence microscopy techniques and permits one to obtain images of planes at various depths within the sample ( sets of such images are also known as z stacks ).

In the Battle of France, members of the Brandenburg Regiment landed by Fieseler Fi 156 Storch light reconnaissance planes on the bridges immediately to the south of the 10th Panzer Division's route of march through the southern Ardennes.

The town had a church, a public pool, a 9-hole golf course, a post office ( 89405 ), and Empire Airport for light planes.

Each town has an airfield, suitable only for light planes.

Among the regrettable high-tech weapons systems he gave the green light to: the MX missile ( still no basing system ), the TV-guided Maverick missile ( fighter pilots become sitting ducks when they launch them ), the F-18 fighter ( costs more, performs worse than the planes it replaced ), the Aquila Remotely Piloted Vehicle drone ( worse than the Israeli version, 16 times as expensive ), the DIVAD gun ( no amount of money could make it work ), and the Apache helicopter ( the Pentagon recently grounded the entire fleet ).

However, until the end of World War II the A-designation was shared between attack planes and light bombers for the Army aircraft ( as opposed to B-prefix for medium or heavy bombers ).

In 1974 the company started to produce Piper Aircraft light planes under license.

For José Ortega y Gasset, light divides the scene into three distinct parts, with foreground and background planes strongly illuminated, between which a darkened intermediate space includes silhouetted figures.

Military experts say a tight naval blockade off Cuban ports and at the approaches to Cuban waters would require two naval task forces, each built around an aircraft carrier with a complement of about 100 planes and several destroyers.

Continuing with the case in which **zg is a Af curve on a quadric Q, we first observe that the second regulus of Q consists precisely of the lines which join the two free intersections of **zg and the planes through any one of the multiple secants.

Large planes juxtaposed with other large planes tend to assert themselves as independent shapes, and to the extent that they are flat, they also assert themselves as silhouettes ; ;

They had courage but their meager training consisted of weekend hops in good weather, in and out of established airports, And the increasingly cold weather soon raised hob with the water cooled engines of their World War 1, planes.

Complete with crowd effects, interruptions by jet planes, and sundry other touches of realism, this disc displays London's new technique to the best effect.

Nowadays most commercial planes are equipped with aircraft flight control systems in order to reduce pilot error and workload at landing or takeoff.

By the 1950s, the development of civil jets grew, beginning with the de Havilland Comet, though the first widely-used passenger jet was the Boeing 707, because it was much more economical than other planes at the time.

For allenes with four identical substituents, there exist two twofold axes of rotation through the center carbon, inclined at 45 ° to the CH < sub > 2 </ sub > planes at either end of the molecule.

An allene with two different substituents on each of the two carbons will be chiral because there will no longer be any mirror planes.

Moscow quickly supplied Bulgaria with T-34 / 85 tanks, SU-100 guns, Il-2 attack planes and other new combat machinery.

In the meantime, Britain should halt the flight of planes armed with nuclear weapons, end nuclear testing, not proceed with missile bases and not provide nuclear weapons to any other country.

The distance is to be taken with the + or − sign, depending on which of the two half-spaces separated by that plane contains p. The y and z coordinates can be obtained in the same way from the ( x, z ) and ( x, y ) planes, respectively.

Dislocations can move if the atoms from one of the surrounding planes break their bonds and rebond with the atoms at the terminating edge.

Face-centered cubic ( fcc ) structures differ from hexagonal close packed ( hcp ) structures only in stacking order: both structures have close packed atomic planes with sixfold symmetry — the atoms form equilateral triangles.

Mikoyan confirmed that talks with Egypt are underway for the sale of 40 Mig-29SMT jet-fighters with a possible additional batch of 60-80 planes.

Because the orbital plane of the Moon is tilted with respect to the orbital plane of the Earth ( the ecliptic ), eclipses can occur only when the Moon is close to the intersection of these two planes ( the nodes ).

In June 1937, the German pocket battleship Deutschland arrived in Gibraltar with dead and wounded after Republican planes bombed it in Ibiza in retaliation for the Condor Legion's bombing of Guernica.

Pei also found the pyramid shape best suited for stable transparency, and considered it " most compatible with the architecture of the Louvre, especially with the faceted planes of its roofs ".

Pei decided that a pyramid was " most compatible " with the other structures at the Louvre, complementing their roofs ' faceted planes.

This is known as anisotropic etching and one of the most common examples is the etching of silicon in KOH ( potassium hydroxide ), where Si < 111 > planes etch approximately 100 times slower than other planes ( crystallographic orientations ).

If the areas of the two parallel faces are A < sub > 1 </ sub > and A < sub > 3 </ sub >, the cross-sectional area of the intersection of the prismatoid with a plane midway between the two parallel faces is A < sub > 2 </ sub >, and the height ( the distance between the two parallel faces ) is h, then the volume of the prismatoid is given by ( This formula follows immediately by integrating the area parallel to the two planes of vertices by Simpson's rule, since that rule is exact for integration of polynomials of degree up to 3, and in this case the area is at most a quadratic in the height.

Perhaps the most serious occurred in an " Air Threat Conference Call " initiated by the National Military Command Center ( NMCC ) after two planes had crashed into the World Trade Center, but shortly before The Pentagon was hit.

In year 2010, Finnair named Tallinn Airport GH as the most punctual ground handling service provider for its planes in Europe and the third best in the world.

Felix Wankel managed to overcome most of the problems that made previous rotary engines fail by developing a configuration with vane seals that had a tip radius equal to the amount of " oversize " of the rotor housing form, as compared to the theoretical epitrochoid, to minimize radial apex seal motion plus introducing a cylindrical gas-loaded apex pin which abutted all sealing elements to seal around the 3 planes at each rotor apex.

The most common arrangement is two complete sets of controls, one for each of two pilots sitting side by side, but in some planes ( military fighter aircraft, some taildraggers and aerobatic aircraft ) the dual sets of controls are arranged one in front of the other ( in tandem ).

As most planes are functionally infinite, disproving anyone's centricity would be impossible.

Some aircraft, like airliners and cargo planes, spend most of their life in a cruise condition.

On September 9, 1944, U. S. Air Force planes swooped in and bombed most of Cagayan de Misamis into piles of rubble, even for the school itself.

Marine flyers shoot down several Japanese planes, but sustain heavy damages on the ground, including several planes on the ground and most of the fuel.

The international counter-terrorism community applauded GSG 9 for the excellent and professional handling of the situation as assaults on planes are considered to be one of the most difficult operations that a hostage rescue force is likely to encounter.

In his review for The New York Observer, Andrew Sarris wrote, " here is the ironic twist in my acceptance of Pearl Harbor-the parts I liked most are the parts before and after the digital destruction of Pearl Harbor by the Japanese carrier planes " and felt that " Pearl Harbor is not so much about World War II as it is about movies about World War II.

According to Allen Weiss, in Mirrors of Infinity, this optical effect is a result of the use of the tenth theorem of Euclid ’ s Optics which asserts that “ the most distant parts of planes situated below the eye appear to be the most elevated .” In Fouquet ’ s time, interested parties could cross the canal in a boat, but walking around the canal provides a view of the woods that mark what is no longer the garden and shows the distortion of the grottos previously seen as sculptural.

Several ferries provide regular transport for most travelers ; the island also features a number of marinas, as well as a small airfield for private planes.

Setting, violence, objectionable language, and ( most ) character fatalities were altered or eliminated by cutting scenes, dubbing, and explanatory voiceovers ( for instance, claiming that the city had been evacuated before a battle scene that would show the incidental destruction of buildings and houses, as well as explaining away the destruction of the Earth armies and air forces as being robot tanks and fighter planes ).

Most versions of Microsoft Flight Simulator include some of the world's most popular aircraft from different categories, such as the Mooney Bravo and Beechcraft Baron 58, which fall into the general aviation category, the Airbus A321 and Boeing 737, which fall into the civil jets category, the Robinson R22, which falls into the helicopter category, and many other planes commonly used around the world.
