About this book
In May 1970, Aerial Photographs Revealed what U.S. military intelligence believed was a Pow camp near the town of Son Tay, twenty-three miles west of North Vietnam's capital city. When American officials decided the prisoners were attempting to send signals, they set in motion a daring plan to rescue the more than sixty airmen thought to be held captive.On November 20, a joint group of volunteers from U.S. Army Green Berets and U.S. Air Force Special Operations Forces Perfectly executed the raid, only to find the prisoners' quarters empty; the POWs had been moved to a different location. Initially, the Son Tay raid was a devastating disappointment to the men who risked their lives to carry it out. Many vocal critics labeled it as a spectacular failure of our nation's intelligence network. However, subsequent events proved that the audacity of the rescue attempt stunned the North Vietnamese, who implemented immediate changes in the treatment of their captives. The operation also restored the prisoners' faith that their nation had not forgotten them.John Gargus not only participated in the planning phase of the Son Tay rescue, but also flew as a lead navigator for the strike force. This revised edition incorporates the most recent information from raid participants and also includes recent translations of North Vietnamese perspectives. No previous book on this top-secret action has given such a full account or such insight into both the execution and aftermath of Son Tay. This book will be an invaluable addition to the history and historiography of the Vietnam War.

    Great single rotor, four channel helicopter!!

    I purchased my Double Horse 9116 from a seller on Ebay. Got a great deal on it as well ($89.88- current price) with free shipping. I was very pleased with my experience from the Ebay seller.What's in the box?You will receive a very nice looking DH9116 4 channel electric helicopter measuring 19.5 inches in length if you stretch the main and tail rotors out front to back and measure tip to tip. It stands 5.5 inches tall if measured from the bottom of the skids to the top of the main rotor assembly. Main rotor length is 15 inches. The DH9116 is fully assembled and ready to fly (after it's charged). You will also receive a four channel, mode 2 radio with a high/low rate switch and four trim buttons. The radio also sports a lighted LCD screen that shows trim and stick positions as well as battery life. The menu button allows for stick reversing and set up for left or right handed flyers. You will also receive a wall charger, plug and manual.What is "Mode... 5/5 Kenneth Marcum "Harley Man" (Fort Wayne, IN. USA) - See all my reviews, December 30, 2011

    Big step up from the toy 3ch copters

    Someone already wrote a really nice review of this copter so I'll keep this fairly short. First and foremost, if you think you know how to fly helicopters from flying 3ch coaxial helicopters, you don't. Although they have provided you with some of the physics of rotary flight, they've also provided you with a huge comfort level in that they are able to hover continuously. Forget most of that with this one.A 4ch single rotor is getting the user closer to collective pitch flying will still providing a greater degree of safety via being able to hover for brief periods and with some input from the flyer. More challenging but a lot more fund when you've mastered it. This is a great beginner copter for someone who hopes to progress to 6ch CP and likes to fly outdoors. Most coaxials do very poorly in the wind, this does better. Still not great but able to be confidently flown in 5mph breezes.The copter itself is very well made IMO. Real hobbyists will... 5/5 tom4416 "bookie monster" (Virginia) - See all my reviews, January 18, 2012

    Love flying this heli! Great value.

    This was an upgrade from my strictly indoor Syma S107/S107G R/C Helicopter - Red dual-rotor helicopter. I had mastered the easy 3-channel Syma, and wanted to try a single rotor 4-channel. I have never flown any RC helicopters prior to the Syma, nor do I have any real-life aircraft piloting experience.Your experience may differ from mine, but thought I would share. I do not think the 9116 is an indoor helicopter, as it requires a lot of free open space to safely fly (without damaging the helicopter). It takes about 1.25 to 1.5 hours to fully charge the helicopter, and once you are used to flying this heli, it will be a LONG 1.5 hours to wait! It is slightly idiosyncratic at times, but "resets" easily when you turn off and turn on the helicopter (when it starts to act erratically after a full charge, at the beginning of your flight). Sometimes if you get if off the ground to about 3 to 5 feet you may notice the erratic behavior disappear (which may be due to "ground... 5/5 ppmd "Professional" (Arizona, USA) - See all my reviews = Durability:, February 11, 2012
