51- The factions in such regions were thought unlikely to have the kind of weaponry that could reach a target at such altitudes".
52- International jets generally fly at altitudes between 30,000 and 45,000 feet, but airlines are notified about ash plumes at all levels.
53- Incidents like these show that the margin for error at higher altitudes is smaller than at takeoff or lower down, say industry experts.
54- Top storylines An artist's conception shows the rocket on NASA's Low-Density Supersonic Decelerator sending the craft to near-space altitudes.
55- A few weeks later, rebels shot down a Ukrainian Antonov 26, a military transport plane that can fly at altitudes of up to 7,500 meters (24,750 feet).
56- ; Penitentes : Tall blades of snow found at high altitudes.
57- The Piccard family was more interested in science at high altitudes and in flying for the joy of it than in setting records.
58- The Köppen climate classification of the region is Cwa (Tropical on high altitudes, humid/warm summer and a dry/cool winter).
59- Furthermore, sprint athletes perform better at high altitudes because of the thinner air, which provides less air resistance.
60- From 1941, the dark earth was replaced by "Ocean Grey" and Sky with "Sea Grey" giving a pattern more suited to higher altitudes.
61- The postwar years saw a rapid conversion to jet power, which resulted in enormous increases in speeds and altitudes of aircraft.
62- The "solution" to this problem was to fly at low altitudes, minimizing the radar line-of-sight and thus minimizing exposure time.
63- The purely space applications design of this ship makes it inappropriate for powered flights at low altitudes, in dense atmosphere.
64- They cover altitudes from approximately 1200 feet above ground level (AGL) to 18,000 feet (5,486 meters) above mean sea level (MSL).
65- The FIM-92B can attack aircraft at a range of up to 15,700 feet (4,800 m) and at altitudes between 600 and 12,500 feet (180 and 3,800 m).
66- To some extent, supersonic aircraft also manage drag by flying at higher altitudes than subsonic aircraft, where the air density is lower.
67- These conditions allowed the Incas to grow species of plants native to lower altitudes that otherwise could not have flourished at this site.
68- NDB signals follow the curvature of the earth, so they can be received at much greater distances at lower altitudes, a major advantage over VOR.
69- Gas turbine engines operate efficiently at much higher altitudes, are far more reliable than piston engines, and produce less vibration and noise.
70- The squadron had mainly been trained in the ground attack role, and had difficulties when assigned to bomber escort duty at sub-optimum altitudes.
71- The Chittagong Hills rise steeply to narrow ridge lines, generally no wider than 36 meters, with altitudes from 600 to 900 meters above sea level.
72- In Somalia it was demonstrated that slow moving/stationary aircraft at low altitudes could be defeated with unguided anti-armour infantry weapons.
73- The system can engage aircraft flying at altitudes from very low altitudes up to 5000 m (16,500 ft), and flying at speeds up to 500 m/s (1,125 mph).
74- Those that reached land were either released within a mile of shore, or at altitudes higher than planned, allowing them sufficient gliding altitude.
75- It was originally developed for the 6-pounder naval gun, for close-in defence and also against targets at intermediate altitudes of ft ( ) to ft ( ).
