    iTunes illegally charging tax

    If Apple has a retail store in that state, then they can charge tax for online sales in that state as if it was an in-state sale.

    GPS System Failure Imminent

    Lots of info here: http://www.gps.gov/systems/gps/modernization/ Seems like they have been rolling out new satellites fairly regularly (in relative terms), with more on the way. The page below details when each "generation" was launched: http://www.gps.gov/systems/gps/space/#generations

    NVGs in GA?

    Current goggles, such as the AN/AVS-6s and 9s are so far ahead of the PVS-5s that they are simply not comparable. My initial training was on PVS-5s, then PVS-7s, and now I'm using AVS-9s. I am edging up on 900 hours of goggle time, but sadly it's as a crew chief, not a rated aviator...so it...

    Inside Combat Rescue

    I'm a crew chief. I've never worn one. In fact, I think only two of our crew chiefs (out of about 30) actually use them. For us, it's because we have our visors up for goggle use, and 99% of our flights are at night. And the MFS doesn't help much with the visor up.

    Inside Combat Rescue

    It's called a Maxillofacial Shield (MFS), and you have the purpose correct. It's just a snap-on piece to the standard HGU-56/P helmet. http://www.gentexcorp.com/default.aspx?pageid=2922

    New iLevil For iPads

    In an iDevice? You don't calibrate it. It is calibrated when the chip is built. One could argue that MEMS gyroscopes are so sensitive and stable that they don't need to be calibrated (They are quite resistant to drift over time and temperature compared to "typical" gyroscopes). One could...

    New iLevil For iPads

    Yeah current iDevices have a three-axis gyro in addition to the three-axis accelerometer. For more info you can search for "mems gyro" to see how it works.

    How much TT is too much TT?

    My flying club is selling a 1979 Piper Arrow IV that has 14,200 hours on it. It's leaves a bit to be desired in some areas but it flies just fine! Price is set at $20k. http://www.controller.com/listingsdetail/aircraft-for-sale/PIPER-ARROW-IV/1979-PIPER-ARROW-IV/1272825.htm

    The most expensive weapon ever built

    Well I've seen it work on a Black Hawk in testing, so clearly the technology works. Whether or not it works in the F-35 may be a different story.

    Realistic aviation movies?

    I'm wondering if you would expand on this. The book is labeled "Historical Non-fiction" rather than a novel, as you suggest. I'm also curious what was significantly changed from the book to the screenplay. If you'd rather not discuss it in the forum, a PM would be appreciated.

    The most expensive weapon ever built

    Why no mention of the F-35's Distributed Aperture System? Besides the fact that it sort of renders the blind spot issue moot?

    AH1 Cobra crashes during the filming of Top Gear

    http://www.ntsb.gov/aviationquery/brief.aspx?ev_id=20120217X34147&key=1 Also, speculation that I've heard claims possibility of a jack stall, also called servo transparency or reversibility.

    AH1 Cobra crashes during the filming of Top Gear

    It was a civilian owned and operated aircraft. I think it was the Korean version of Top Gear.
