Some air shows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers.

Some smaller designs have been used as the basis for specialist fighters, such as night fighters, and a number of fighters, such as the Hawker Hurricane were used as ground attack aircraft bombers, replacing earlier conventional light bombers that proved unable to defend themselves and carry a reasonable bombload.

Some of the maneuvers include both solo aircraft performing at once, such as opposing passes ( toward each other in what appears to be a collision course ) and mirror formations ( back-to-back.

Some of the most expensive fighters such as the F-14 Tomcat, F-22 Raptor and F-15 Eagle were employed as all-weather interceptors as well as air superiority fighter aircraft, while commonly developing air-to-ground roles late in their careers.

Some aircraft, the Panavia Tornado for example, retain a very basic hydro-mechanical backup system for limited flight control capability on losing electrical power, in the case of the Tornado this allows rudimentary control of the stabilators only for pitch and roll axis movements.

Some notable mass fractions are found in the following table ( some aircraft are included for comparison purposes ):

Some aircraft are equipped with CCTV cameras, so the pilots can monitor the cabin activity.

Some are so serious about realistic simulation that they will buy real aircraft parts, like complete nose sections of written-off aircraft, at aircraft boneyards.

Some GEVs are able to fly higher out of ground effect ( OGE ) when required-these are classed as powered fixed-wing aircraft.

Some aircraft, like fighter planes or experimental high speed aircraft, require very high excess thrust to accelerate quickly and to overcome the high drag associated with high speeds.

Some small propeller-driven aircraft engines still use the updraft carburetor design.

Some coaches are equipped with lap belts, as are passenger aircraft seats.

Some of the noteworthy types produced by Fokker during the second half of the war included the Fokker D. VI, Fokker Dr. I Dreidecker ( the mount of the Red Baron ), Fokker D. VII ( the only aircraft ever referred to directly in a treaty: all DVII's were singled out for handover to the allies in their terms of the armistice agreement ) and the Fokker D. VIII.

Some lower-compression piston engines can operate on unleaded mogas, and turbine engines and diesel engines — neither of which requires lead — are appearing on some newer light aircraft.

Some aircraft also feature air brakes designed to reduce their speed in flight.

Some large aircraft from the 1950s ( including the Canadair Argus ) used free floating control surfaces that the pilot controlled only through the deflection of trim tabs, in which case additional tabs were also provided to fine tune the control to provide straight and level flight.

Some, she knew, looked upon Thompson almost as a saint, but others read in `` The Hound Of Heaven '' what they took to be the confessions of a great sinner, who, like Oscar Wilde, had -- as one pious writer later put it -- thrown himself `` on the swelling wave of every passion ''.

Some of the persons listed are, like Korzybski, polymaths and several categories apply to them.

Some consider this more of a short story collection ; Milne didn't like it and considered The Day's Play as his first book.

Some fruit segments ( like those in Daucus spp.

Some, like Rambert, are exiles in double measure since they are not only cut off from those they want to be with but they do not have the luxury of being in their own homes.

Some others, like in Europe wanted republican independence as the French and Americans.

Some scholars argue Plato drew upon memories of past events such as the Thera eruption or the Trojan War, while others insist that he took inspiration from contemporary events like the destruction of Helike in 373 BC or the failed Athenian invasion of Sicily in 415 – 413 BC.

Some operations may change the state of the ADT ; therefore, the order in which operations are evaluated is important, and the same operation on the same entities may have different effects if executed at different times — just like the instructions of a computer, or the commands and procedures of an imperative language.

Some, like Hernando De Soto, argue that much of the poverty in the Third World countries is caused by the lack of Western systems of laws and well-defined and universally recognized property rights.

Some acids like tariric acid contains an alkyne group.

Some authors see a centralized peer – review process as less relevant and publish on their home pages or on unreviewed sites like arXiv.

Some systems are vacuum-insulated, acting something like large thermos bottles.

Some scenes, like Evil Ash walking along the graveyard while his skeleton minions come to life, blended stop-motion animation with live skeletons that were mechanically rigged, with prosthetics and visual effects.

Some encrusting bryozoan colonies with mineralized exoskeletons look very like small corals.

Some companies such as Topdeck Travel were set up to specifically use buses to drive the hippie trail or travel to places like north Africa.

Some Hilbert spaces, like, have finite dimension, while others have infinite dimension.

Some properties of this notation are convenient since we are dealing with linear operators and composition acts like a ring multiplication.

Some old characters, like The Three Bears and Little Plum, have more recently made a return.

Some questions are still unanswered, such as the inclusion in the BCI repertoire of some characters ( currently about 24 ) that are already encoded in the UCS ( like digits, punctuation signs, spaces and some markers ), but whose unification may cause problems due to the very strict graphical layouts required by the published Bliss reference guides.
