Creator: John Gargus | 2010-09-28

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 (126 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

    Rating (107 reviews):

    Capable, Durable, and Fun Quadcopter!

    The Syma X1 is an excellent entry-level quadcopter. It is durable (already survived 100+ crashes), relatively easy to fly, and an impressive value. It is suitable for indoors and outdoors use and I can't recommend it enough for any looking to get into R/C quadcopters or simply looking for something fun to try out.Design/Build:The Syma X1 is a very basic model - it has the four propellers, plastic frame, small electronics board, and a thin plastic cover (either a UFO, Bumblebee, or Spaceship - simply aesthetic). It is very light and the battery (included) clips into the undercarriage of the craft. I was surprised at how durable this quadcopter was - I've crashed it countless times into walls, ceilings, down the stairs, etc. Each time I cringe slightly at the sound, but the worst that has happened is the battery has popped out. Also, Syma includes an extra set of propellers in case you do damage any of them.Remote Control:Again, a very... 5/5 Arbitrage (Boston, MA) - See all my reviews = Durability:, March 14, 2013

    Good starter Quad, or a toy for grown-ups

    Customer Video Review Length:: 3:00 MinsThis thing ROCKS! Crash resistant, lightweight, simple to set up. Quad is a throw away toy for me to move up to build my own. I am experienced in the RC world, so this review may not be for everyone... I'm not using the original controller, not enough power, and the antenna is probably a tube dipole. Mine is bound to my FlySky CT6B transmitter. I get about 3 times the range. This thing flys stable. I just opened a couple of other batteries and soldered JST plugs onto the single cells, and off we went. It even flys with an old Zippy 1500 mah. It also flys ok with a #808 #16 camera. I'll try and post the video. The receiver uses GFSK modulation like the Turnigy, FlySky, and HobbyKing setups, so they should be compatible. Look online RCgroups for setup parameters. If you like RC, Just throw it in your cart. I got this one for 30, so it was a no-brainer...costed same as my wife's haircut. Parts widely available, Great for windy and rainy days when I can't fly my... 5/5 Patrick Heidingsfelder (South MS) - See all my reviews, July 14, 2013
