The incident showed that even high-altitude aircraft were vulnerable to missiles.

Consequently, nearly all high-speed and high-altitude aircraft use jet engines.

If they become overloaded with targets, priority would be given to high- speed, high-altitude aircraft.

The atmosphere filters most of these, so they are primarily a concern for spacecraft and high-altitude aircraft.

This program focused on producing a missile which could bring down a large, non-maneuvering, high-altitude aircraft.

A high-speed, high-altitude aircraft might fly over early warning radars without being recognized.

Later generations invented pressure suits and high-altitude aircraft.

This means that a high-altitude aircraft is only visible to the operator in a narrow ring at the extreme outside of the scope.

The air campaign has been conducted until now using cruise missiles and precision-guided bombs dropped from high-altitude aircraft.

Venture capitalists began financing companies with plans to deliver data quickly to computer users in other ways, like using satellites and even high-altitude aircraft.

These jets combine transatlantic capability with the speed and comfort of a wide-body, high-altitude aircraft.

Although the wreckage was spotted by high-altitude aircraft, no one has been allowed near the site in an area presumed to be controlled by guerrillas.

Some entrepreneurs were so optimistic that they suggested sending high-altitude aircraft to circle above big cities, beaming signals down to consumers.

These intensive measurements of the Antarctic ozone were made mainly by high-altitude aircraft and balloons, but cost limits their frequency.

There have also been efforts to launch satellites from a sea platform in the Pacific, as well as from high-altitude aircraft.

Other loads that may be critical are pressure loads (for pressurized, high-altitude aircraft) and ground loads.

SNCAC continued work on high-altitude aircraft, proposing two pressurised bombers in 1938.

New computer programs to be tested soon are intended to allow controllers to monitor all high-altitude aircraft with five-minute updates and provide an analysis of the traffic.

The technique, visible and near-infrared imaging spectroscopy, measures nitrogen and water in the forest canopy using an instrument aboard a high-altitude aircraft.

With the development of high-altitude aircraft, early-detection radar antennae were shaped to produce a beam with a vertical cross-section of 30 to 40 degrees.

Stapp's work resolved that problem as well as many others, which allowed the next generation of high-altitude aircraft and the HALO insertion techniques.

In the late 1980s the G 520 Egrett/STRATO 1 high-altitude aircraft was produced which established five world records.

The majority of high-altitude aircraft engines used during World War II used mechanically-driven superchargers, because these had three significant manufacturing advantages over turbochargers.

Volacom worked closely with Burt Rutan at Scaled Composites to design a specialized high-altitude aircraft platform using a novel hydrogen-powered electric power plant.
