In Korea‚ helicopters would pick up a single wounded soldier that was attached to a stretcher on the outside of the helicopter. This aircraft would then fly to a Mobile Army Surgical Hospitals or M.A.S.H. Here the wounded individual would be treated by medical teams for their injuries. Many soldiers died before they

Also among these contributions are the helicopter rotor and propeller‚ paper‚ and the seismograph. The helicopter rotor and propeller was invented in the Fourth Century CE and was a common toy called the Bamboo Dragonfly and now is used in modern aeronautics. The Seismograph was invented in the Second Century CE by Chang Heng to

not precise enough as in ICBMs‚ or for the stabilization of flying vehicles like radio-controlled helicopters or unmanned aerial vehicles. Due to their precision‚ gyroscopes are also used in gyrotheodolite to maintain direction in tunnel mining. Within mechanical system or devices‚ a conventional gyroscope is a mechanism comprising a rotor journal to spin about one axis. The journals of the rotor being mounted in an inner gimbal ring. The inner gimbal is journal for oscillation in an outer gimbal

THE RECUPERATOR EVOLVED ARTILLERY 2 Field Artillery has been an essential part of every army because of how necessary it is to win a war. Any country who had the most advanced and supplied artillery would be the most advantaged army to win. So the little improvements being made over the years to the different kinds of guns were essential to remain a strong fighting force. There have been many advances made in artillery from

the Vietnam War. The jungle terrain of Vietnam was rough‚ wet‚ and thick. This terrain caused trouble to ground vehicles. The result of this was the extensive use of helicopters. The helicopter could fly over large amounts of jungle at quick speeds‚ and easily perform tasks without the need of a landing strip or airfield. US helicopters flew a total of more than 36 million operations during the Vietnam War. Many different models were produced‚ but the UH-1 Iroquois was the most produced and consequently

INTRODUCTION MOVIE TITLE: A GOOD DAY TO DIE HARD SYNOPSIS: In Moscow‚ a high ranking but corrupt Russian official named by Victor Chagarin (Sergei Kolesnikov) planned on incriminating a political and government whistleblower‚ Yuri Komarov (Sebastian Koch) without even taking him for justice when he refused to cooperate and hand over a confidential file that was believed to have convicting evidence against Chagarin. While in another situation‚ Jack McClane (Jai Courtney) was arrested under

I would use Chicken Little in second-grade as part of the core standards in the genre of folktales. The students can use skills and strategies for comparing texts. I would use Steven Kellogg’s retelling alongside a more traditional re-telling such as Paul Galdone’s version in order to make comparisons between the two and have the children decide which version they enjoyed more. Summary: In this version of Chicken Little‚ the focus is more on the character Foxy Loxy‚ who is portrayed as an escaped
