NASA Dryden UAV pilot
I have a pretty interesting job here at Dryden. I get the opportunity to fly some great unmanned aircraft and work with some very talented people.
I may be the only pilot signed off in the DROID – Dryden Remotely Operated Integrated Drone – as well as the Ikhana (NASA MQ-9) and Global Hawk (NASA RQ-4). These aircraft all play a vital role in NASA’s research mission but their performance and the way they are flown are very different. The DROID is a very sophisticated platform capable of autonomous flight. Though to the untrained eye it looks like a remote-controlled toy, it really isn’t; it has an autopilot, cameras, a pitot static system and brakes. It is flown through a ground system comprising a series of computers and monitors housed in a “bread van.” This aircraft is flown using “stick and rudder” skills, which basically means the pilot operates a stick to fly it.

The Ikhana (a modified Predator) is also flown this way. Pilots fly the Global Hawk, on the other hand, using a keyboard and mouse. The size of these aircraft range from 10-foot wingspan and 57 lbs. (DROID) to a 66-foot wingspan and 10,500 lbs. (Ikhana) to a 116-foot wingspan and 25,600 lbs. (Global Hawk). There are all kinds of missions; local DROID flights are flown at altitudes of just 1,000 feet and less than one hour over the small UAS airspace here at Edwards. Ikhana missions vary, but may have the aircraft flying fire missions over the western United States at altitudes over 20,000 feet and for up to 20 hours at a time. The Global Hawk has seen missions over the Arctic, the Pacific and the Atlantic, altitudes of over 60,000 feet and missions lasting more than 20 hours.
Amazing platforms are being flown here at Dryden, and the technology is constantly being improved. Keep an eye on the fascinating world of unmanned aircraft!

This post is exactly what I am interested. keep up the good work. we need more good statements. Please add more good information that would help others in such good way.
