Officials: C-17 crash report not true.
An Air Force C-17 did not crash Monday morning in Olney, Texas, contrary to a CNN report, according to Mike Kucharek, an Air Force spokesman at North American Aerospace Defense Command.
A C-17 out of Altus Air Force Base, Okla., was flying over Olney, which is about 130 miles west of Dallas, during a training mission, but the crew returned safely, said service spokesman Ed Gulick.

NOE is used to minimise detection by hostile aircraft, by AWACS surveillance and control systems, by ground-based radar or by the actual targets of the attack (such as when setting up a helicopter strike against an armored force).
A high-flying aircraft would be detected by defense systems at long range, allowing an air defense system time to react, alert SAM and AAA systems and scramble fighter (Air Defence) aircraft. Using NOE flight, the approach may be undetected, the aircraft "pops up" to attack the target and then turns to escape before the enemy can respond. Doppler radar has the potential to detect NOE flight but the incoming aircraft has to be within radar range in the first place and low flying minimises this possibility.
Heights Above Ground Level (AGL) in NOE and low flying generally vary with the aircraft speed, aircraft maneuverability and the ruggedness of the terrain. Helicopters are capable of flying down to a few feet below the skids or wheels. Fast jets are more constrained and at a typical low-flying speed of 450 knots (800 km/h), 200 feet (60 m) is not unusual and 50 feet (15 m) is possible in relatively flat terrain. Power wires are a danger to all aircraft flying at low level and 'wire strikes' are not uncommon. Special maps are produced that plot the routes of these wires but these are difficult to keep up-to-date, especially for foreign/enemy countries. Pilots are trained to scan for the pylons or power-poles that support these wires, because they can be seen at a distance where the wires themselves cannot.
