The Son Tay Raid, American POWs in Vietnam Were Not Forgotten

Creator: John Gargus | 2010-09-28

There they would provide fuel for two Air Force Combat Apple RC-135Ms and for one radio relay RC-135. ... Their aircraft would be configured with additional equipment to monitor four more UHF channels used by the raiders.

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.

    Weeeeeeeeeeeeeeee!

    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.

    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... 5/5 Kevin - See all my reviews This review is from: New with Video Camera!

    Great little toy

    Most of the other reviews have hit the major pros and cons with this, but there are still a few more that I can add. Hope they help in making your purchasing decisions!PRO:- Thanks to the gyro, very short learning curve. Remote has two joysticks. Left side only moves up/down and controls speed of the rotors, which controls how much lift they generate. Right joystick moves up/down (controlling forward/reverse) and left/right (makes heli spin). You can also moving the right stick diagonally to make various turns while moving forward or backwards (reverse "figure-8's" are always impressive).- Surprisingly large number of "mods" that can be done to a $30 heli. After experimenting, I have settled on two minor ones. First, I removed the spring from the left joystick in the controller. This lets me put the heli in a hover and let go of the remote ("look ma, no hands!"). I have also moved the landing gear forward in their mounts to push the center of... 4/5 RJ (NY, NY) - See all my reviews Most of the other reviews have hit the major pros and cons with this, but there are still a few more that I can add.

    Very Cool RC Helicopter with GYRO- Great for Beginners

    Customer Video Review Length:: 0:19 MinsThis Syma S107G 3.5 Channel RC Helicopter with GYRO great for beginners, like myself. It has a sleek design made of metal and plastic. The helicopter we received is blue, white, black, and silver. It is an awesome price for as well as it works. We have bought others in store for twice the price and they did not work this well. It has a flight time of 7-10 minutes for every 50-60 minutes charged.It requires six AA batteries to power the controller. These batteries are not included. We are learning with this helicopter and it has taken quite the beating. I am literally surprised that we haven't broke it yet. I am very pleased with the quality. It has four blades and gyro that helps it stay steady in flight. It is fairly easy to control. The controller has two different joy sticks. One joy stick is for throttle and the other is to control. It also has a knob for trim. (Keeps the helicopter from spinning left to right when you fly it.) The... 5/5 Amazon Customer (USA) - See all my reviews, August 2, 2015

    A great little toy for newbies at RC helicopter flying!

    My husband and son have always been awed with the RC helicopters they sell and demo at the mall that they will spend time watching it over shopping. We have 2 RC cars at home which is always a great bonding time for them. So when I surprised them with this Syma 107G RC Helicopter and the Helicopter Landing Pad that perfectly goes with it, they were ecstatic to try it out.This helicopter came in packaged nicely, ready to be given as a gift. It included a helicopter (we got the blue), a yellow USB charger, an infra-red remote control, and a user manual. Instructions were easy to follow. Initial charging did not take long, about 45 minutes and can be done in 2 ways. Connecting the USB cord from the helicopter to either the remote control (after putting in 6 AA size batteries), or plugging the other end of the USB cable to a computer or USB port.Flying the helicopter as a newbie is a little bit tricky but my husband got the hang of it after couple of tries.

    Had promise, but amazing customer service (HalleyRUs)

    0 4/5 Travis Turner - See all my reviews Verified Purchase(What's this?) This review is from: Helizone Lightning Bird WL V911 4 Channel Single Rotor 2.4 Ghz Remote Control Helicopter - Special Edition with upgraded battery (Toy) well to be frank this thing is cheap feeling. I right away did not feel like I got my $50 worth. During every flight it had the "toilet bowl" effect. (Where the heli faces the same direction but going around in a horizontal circle)This effected the flight of the helicopter a lot. After about 5-6 light crashes the pins on the back of the battery attachment started getting loose, making the vibration from flight....disconnect the battery making the heli drop from the air.Edit:Within hours of the review above being posted Halley R US contacted me via email offering a replacement device that would be in house tested and guaranteed working. This is by far the best customer service I have gotten online.If you feel like your heli is not working as advertised, do not hesitate to contact them, they are great. Even though my original score was 2 stars, the service alone gives it two more. 0 Help other customers find the most helpful reviews  Was this review helpful to you? , December 27, 2012

    Great First Helicopter

    I have been looking at R/C helicopters on Amazon for over a year now. When the second Christmas went by and Santa still did not come through for me, I decided to take matters into my own hands. I chose the Lightning Bird because I wanted something with 4 channels, and the value seemed pretty good.This is my first R/C helicopter, and I was worried about how difficult it would be to control. Out of the box, it was nearly impossible to fly - I was constantly fighting it and thought I had made a mistake. Even after maxing out the trims, it still wanted to veer out of control. I noticed the right servo arm did not sit horizontal when first powered up, and I measured the left actuator rod and noticed it was longer than the right. I adjusted the servo & rod and moved the attachment points to the inner holes and wow, what a difference. With minimal trim adjustment I was able to get it to hover in place just like so many other people had mentioned in their reviews.
