McDonnell Aircraft later merged with the Douglas Aircraft Company to form McDonnell Douglas in 1967., Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organisations research, design, manufacture, operate, or maintain aircraft and/or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications., A rotorcraft or rotary-wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotary wings or rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor. The International Civil Aviation Organization (ICAO) defines a rotorcraft as "supported in flight by the reactions of the air on one or more rotors". Rotorcraft generally include those aircraft where one or more rotors are required to provide lift throughout the entire flight, such as helicopters, cyclocopters, autogyros, and gyrodynes. Compound rotorcraft may also include additional thrust engines or propellers and static lifting surfaces., A rocket (from Italian "rocchetto" "bobbin") is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine. Rocket engine exhaust is formed entirely from propellant carried within the rocket before use. Rocket engines work by action and reaction and push rockets forward simply by expelling their exhaust in the opposite direction at high speed, and can therefore work in the vacuum of space., The Douglas Aircraft Company was an American aerospace manufacturer based in Southern California. It was founded in 1921 by Donald Wills Douglas, Sr. and later merged with McDonnell Aircraft in 1967 to form McDonnell Douglas.

Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled., Subject: american airlines fleet, Relation: item_operated, Options: (A) 4 (B) aircraft (C) airliner (D) spacecraft

[EX Q]: Context: Punta del Este is a city and resort on the Atlantic Coast in the Maldonado Department of southeastern Uruguay.

While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows: 
European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity., Suite Punta del Este is a tango nuevo work for orchestral strings and a bandoneón written by the Argentine composer Ástor Piazzolla in 1982 .

In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., Hedwig Courths - Mahler ( he : tviç kurts ma : ler ) , née Ernestine Friederike Elisabeth Mahler ( February 18 , 1867 , Nebra / Unstrut -- November 26 , 1950 , Rottach - Egern , Bavaria ) was a German writer .
