Comment the usual suspects (Score 3) 17

What megalomaniacal near-trillionaire had a whole squadron of leet hackers hoovering up federal employee records just a few short months ago? I forget. It musta been somebody with pockets 30x deeper than George Soros to tunnel into those boring databases, we should launch an investigation.

Comment Hematite vs Rust (Score 5, Informative) 20

Hematite is one specific type of iron oxide. Rust is a non-technical umbrella term for all iron oxides, and the typical red ones we see in daily life are formed by contact with water and are not hematite. Hematite is a dark charcoal gray and is sometimes formed as a byproduct of iron ore processing or other heat and pressure processes in the ground, where oxygen may be present but not water.

Comment Re: "far too small to generate any lift"?? (Score 4, Interesting) 106

That's how I read it. It should say it has no thrust.

A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.

For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.
