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.

    Rating (162 reviews):


    This is my second one. I broke the first using a pipe to get it out of a tree. Why buy another? It is without a doubt the best rc video helicopter I have received here. I intend to buy several more so I can rotate them when I am out and about flying them. Keeping one charged while we fly the others....thats how much fun these are. Durable? You bet! Outdoor flying? Not the greatest if there are any winds aloft at all, but on a calm day, there is nothing better than flying this toy over and over and videotaping your exploits. I have flown up to about 30 meters, and could have gone higher, but the darned thing was hard to see. Incredibly stable, you will find yourself flying this helicopter through increasingly more difficult paths, as it is rock steady when it is calm out.BUY THIS! for the money, it is amazing.As with anything, there are pros and cons. I guess in keeping with the other comments, the cons of this helicopter is that flying outdoors is a challenge if there is any... 5/5 Dave Francis (Bellevue, WA, US) - See all my reviews = Durability:, December 1, 2012

    Nice all black, good quality camera, stable flight.

    I received this today and charge it right away for test flight. It is very solid, as nice looking as Syma brand S031G only a bit smaller. Charging time is 20-30 min, and flight time is 5-7 min quite short. If you can upgrade the battery to keep it longer in the air that would be more fun. The 2.4G transmitter is neat, it's not bulky and has an electronic display. Binding take some time, i don't know why, my transmitter sometime takes up to full 5 min for it to bind with the black bird. But once they both hooked up, it's fun to fly. Operating the camera/still photo is no brainer. There are one button for each action on the transmitter, on or off, however it take some time to get used to. The slot for the SSD is as easy to operate as in any p/s cameras, insert the card, soft push to eject it. Over all, it's nice. But with the price of $50+, it's a little expensive. The "party light" led display along the tail boom is just sicken me (my kids love it); and annoying as well making it look... 4/5 Kevin - See all my reviews = Durability:, June 26, 2012

    Syma X1 Quad Bind Process / Radio not working

    Hey fellow owners and potential owners!Noticed others are having the same problem my buddies and I had when I first received the Syma X1 Quad, they should UPDATE THE INSTRUCTIONS ASAPI had an issue with the radio transmitter not binding with the Syma X1 quad and there IS A EASY SOLUTION.The instructions are lacking in this area and are responsible I'm sure with a lot of frustration and probably returns.In between my friends and I we have over 6 of these to date, they all work with this procedure that I quickly wrote for another amazon user.SYMA X1 QUAD - RADIO TRANSMITTER BIND PROCESSIMPORTANT SOLUTION TO ALL OWNERS - RADIO NOT WORKING WITH THE SYMA X1 QUAD1.

    how to switch from mode 1 to mode 2

    Excellent little machine. When I first turned it on and tried to fly, it flew sideways into the wall. Tried several times with the same result.solution: First, make sure that transmitter is off. Place battery into unit and immediately place it on the floor or other level surface. Wait for unit to stop flashing rapidly and is flashing slow, THEN make sure that throttle is off and turn on the transmitter, unit will pair with a steady light and an audible beep.Happy flying. Remember it is a 4 channel. I have yet to flip it, just not enough room where I fly indoors and I have yet to determine where the 'A' button is to change it from mode 1 to 2.FOUND IT!! thankfully!!Transmitter offHold right horizontal trim button to the rightPower on transmitterrelease trim buttondisplay now reads Mode 2Myself... I am so much happier with the unit now that I found mode 2. I am used to flying coaxials in this mode and... 4/5 Custom Communications "customcommunications" (massachusetts, usa) - See all my reviews, December 21, 2012

    Tough and Great flying machine

    This is an incredible tough little flying machine and a great way to get in to the world of RC flying and quad copters.I have purchased various indoor and outdoor RC flying toys and this is the first one that has made it intact after the first week.First the toy, it comes with a decent 2.4ghz transmitter with a short rubber antenna which can't break unlike the old steel ones of years gone by. The flying instructions look quite complicated but who really reads a manual anyhow and the only way to learn is by practice and it does take a while.The Quad comes fully assembled and once charged it is ready to fly. Charging time is about an hour and flight time is over 10 minutes. I think continuous fly time would be around 6 - 7 minutes but it will be a good few days until you can keep it in the air for over 1 minute.We have crashed this endless times, landed in the tallest of trees, got tangled in branches, my garden is now littered with long poles... 5/5 furnic (Florida, USA) - See all my reviews = Durability:, November 16, 2012
