High-energy cosmic rays impacting Earth's atmosphere ( or any other matter in the Solar System ) produce minute quantities of antiparticles in the resulting particle jets, which are immediately annihilated by contact with nearby matter.

The Dassault Falcon private jets are built there as well as the military aircraft Rafale and Mirage 2000, the Airbus A380 cockpit, the boosters of Ariane 5, and the M51 SLBM missile.

Although they are the most well known for their small, piston-powered aircraft, they also produce business jets.

Often several jets are used in series to enhance the pumping action.

Its radio lobes are unique in that the polar jets producing them are not particularly powerful, giving the lobes a more diffuse, knotted structure due to interactions with the intergalactic medium.

* 1985 – United States Navy F-14 fighter jets intercept an Egyptian plane carrying the Achille Lauro cruise ship hijackers and force it to land at a NATO base in Sigonella, Sicily where they are arrested.

* 1970 – Two passenger jets bound from Europe to New York are simultaneously hijacked by Palestinian terrorist members of PFLP and taken to Dawson's Field in Jordan.

The elementary quark and gluon particles affected are unobservable directly, but instead emerge as jets of newly created hadrons, whenever energy is deposited into a quark-quark bond, as when a quark in a proton is struck by a very fast quark ( in an impacting proton ) during a particle accelerator experiment.

Compared to rotating wings, due to their high exhaust velocity, jets are comparatively inefficient in hover, but jet engines are compact and this gives advantages when much higher top speeds are needed, such as for fighters.

* August 28 – Seventy-five people are killed and 346 injured in one of the worst airshow disasters in history at Germany's Ramstein Air Base, when three jets from the Italian air demonstration team, Frecce Tricolori, collide, sending one of the aircraft crashing into the crowd of spectators.

Cryogenic liquid jets of helium are another proposed technique, which may

During a display, more than are pushed through its 193 jets.

In this sense the callioflute provides some improvements over the calliope in the sense that the callioflute enables a musician to attain subtle changes in pitch, timbre, volume, and tone, by the way in which the water jets are obstructed with the fingers.

Giotto provided the first evidence in support of Fred Whipple's " dirty snowball " hypothesis for comet construction ; Whipple postulated that comets are icy objects warmed by the Sun as they approach the inner Solar System, causing ices on their surfaces to sublimate ( change directly from a solid to a gas ), and jets of volatile material to burst outward, creating the coma.

Because of this limitation, propellers are favoured for planes which travel at below mach. 5, while jets are a better choice above that speed.

Additional support for strong beaming in GRBs has come from observations of strong asymmetries in the spectra of nearby type Ic supernova and from radio observations taken long after bursts when their jets are no longer relativistic.

Some alternative models replace the black hole with a newly formed magnetar, although most other aspects of the model ( the collapse of the core of a massive star and the formation of relativistic jets ) are the same.

The similarities between the emissions of X-ray binaries such as HDE 226868 / Cygnus X-1 and active galactic nuclei suggests a common mechanism of energy generation involving a black hole, an orbiting accretion disk and associated jets.

At least some accretion discs produce jets, twin highly collimated and fast outflows that emerge in opposite directions from close to the disc ( the direction of the jet ejection must be determined either by the angular momentum axis of the disc or the spin axis of the black hole ).

Microquasars are named after quasars, as they have some common characteristics: strong and variable radio emission, often resolvable as a pair of radio jets, and an accretion disk surrounding a compact object which is either a black hole or a neutron star.

Such jets are believed to be created by the interaction of the central black hole and the accretion disk.

The accretion explains all peculiar properties of classical T Tauri stars: strong flux in the emission lines ( up to 100 % of the intrinsic luminosity of the star ), magnetic activity, photometric variability and jets.

The disk eventually disappears due to accretion onto the central star, planet formation, ejection by jets and photoevaporation by UV-radiation from the central star and nearby stars.

Perpendicular to the accretion disk, a pair of relativistic jets carries a highly energetic plasma away from the AGN.

The inner structure of an Active Galaxy showing the accretion disk and relativistic jets in the vicinity of a supermassive black hole.

In general, accretion from disks is known to produce fast-moving jets, perpendicular to the disk, of ejected material.

Stars are often surrounded by accretion disks in their first few hundred thousand years of existence, which form as gas falls onto them, and the rapid rotation of the inner parts of these disks leads to the emission of narrow jets of partially ionised plasma perpendicular to the disk, known as polar jets.

Because they are associated with the youngest stars, where accretion is particularly strong, infrared bow shocks are usually associated with more powerful jets than their optical HH cousins.

While it is still mostly a mystery to physicists how polar jets are formed and powered, the two most often proposed origins of this power are the central object ( such as a black hole ), and the accretion disc.

While it is not known exactly how accretion discs manage to produce jets, they are thought to generate tangled magnetic fields that cause the jets to collimate.

Similar jets, though on a much smaller scale, can develop around the accretion disks of neutron stars and stellar black holes.

The accretion disc is subject to extreme heating as it spirals into the primary and this heating causes the accretion disc to give off intense X-rays and opposing jets of hot hydrogen along the axis of rotation, above and below the plane of the accretion disc.

The jets from the primary are emitted perpendicular to its accretion disk.

This has prompted theorists ( Soker & Rappaport 2000 ; Frank & Blackmann 2004 ) to investigate whether an accretion disk scenario, similar to the model used to explain jets from active galactic nuclei and young stars, could account for both the point symmetry and the high degree of collimation seen in many PPN jets.

With naked gas jets below and leaky windows above, enough to ruin wall paintings in any medium, they have survived, in a building long unheated in winter, hot and damp under the iron dome in summer.

The Croatian government responded to the blockade of roads by sending special police teams in helicopters to the scene, but they were intercepted by SFR Yugoslav Air Force fighter jets and forced to turn back to Zagreb.

Mihdhar and Hazmi raised some suspicion when they offered extra money to their flight instructor, Richard Garza, if he would train them to fly jets.

* 1976 – Two Imperial Iranian Air Force F-4 Phantom II jets fly out to investigate an unidentified flying object when both independently lose instrumentation and communications as they approach, only to have them restored upon withdrawal.

Two F-16 fighter jets from the 121st Fighter Squadron of the D. C. Air National Guard were scrambled and ordered to intercept Flight 93 ; the pilots intended to ram it since they did not have time to arm the jets.

For example, plumbers use video cameras for inspections of hidden leaks or problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.

As jets became larger, more powerful and faster they required more space to take off and land.

Blue jets differ from sprites in that they project from the top of the cumulonimbus above a thunderstorm, typically in a narrow cone, to the lowest levels of the ionosphere to above the earth.

Meanwhile, the soldiers manage to use the plane's taillights and Morse code signal to the U. S. Navy fighter jets that they are on board and not to shoot them down.

Sometimes they got involved in shootings with the Pakistani jets defending the airspace.

His ouster was due largely to his reluctance to acquire jets, feeling that they were unnecessary and expensive.

The pumps that evacuate these tanks of water are so powerful that they produce large jets of water when the vessel emerges rapidly from the surface of the water.

Carrier battle groups are especially well defended, as not only do they typically consist of many vessels with heavy air defence armament but they are also able to launch fighter jets for combat air patrol overhead to intercept incoming airborne threats.

Because at every point of their path the high-velocity jets are emitting light, the light they emit does not approach the observer much more quickly than the jet itself.

The jets have the most obvious observational effects in the radio waveband, where Very Long Baseline Interferometry can be used to study the synchrotron radiation they emit down to sub-parsec scales.

However, they radiate in all wavebands from the radio through to the gamma-ray via the synchrotron and inverse-Compton process, and so AGN with jets have a second potential source of any observed continuum radiation.

Iraqi Airways had 17 jets, all of which were moved to secret locations, mainly in Jordan ( some were parked on the aprons of Amman's Queen Alia International Airport where they still stand today ).

The higher powered piston engine types that had been too late for World War II were still capable of holding their own against the jets as they were able to both out accelerate and out manoeuver the jets.
