Overview
The C-17 Globemaster III is a flexible cargo aircraft capable of doing airlift, airdrop, and  aeromedical evacuations.

Don’t worry if you’re not familiar with these terms, to put it simply the C-17 carries a lot of stuff far distances.

The bases it operates from in the US Air Force are: Travis AFB, CA; Dover AFB, Delaware, Joint Base Lewis-McChord, WA; Joint Base Charleston, SC; Joint Base McGuire-Dix-Lakehurst, NJ; Joint Base Elmendorf-Richardson, AK; Joint Base Pearl Harbor-Hickam, HI.

概述

C-17 全球霸王 III 是一款可以容許許多配置的運輸機，並且兼容空運物資、隔空投送並且也有空中醫療的作用。

別擔心，如果你對這些術語還不了解的話，

簡單來說，這架C-17載運各種種類的東西並且可以飛行很長的距離。

目前在美國空軍執勤的基地有：加州的特拉維斯空軍基地、德拉威爾州的多佛空軍基地、華盛頓州的劉易斯-麥克德聯合基地、南卡羅來納州的特拉維斯空軍基地、新澤西州的麥圭爾空軍基地、阿拉斯加州的埃爾門多夫空軍基地、珍珠港-希卡姆聯合基地。

Now let’s take a look at some of its characteristics:

現在一起來看看這架C-17麋鹿的特點：

Note:

*Mach is the measurement of speed relative to the speed of sound.

Mach 1 is the speed of sound.

Most of you are moving at less than Mach 1.

If you find yourself in a high performance jet or hurtling through the atmosphere you may experience speeds greater than mach 1.

*The loadmaster is responsible for coordinating and making sure anything transported on the plane is safe and

secure.

*Knot is the measurement of speed. 1.852km/h

註記：

*馬赫是音速的單位1 馬赫 =（340 m/s）。

可以想像一下，我們人在生活中的移動速度基本上很少超越1馬赫，

如果你正搭乘高能的噴射機或空中穿梭，那你很可能經歷高於1馬赫的速度了。

*裝卸長: 是負責機上調解和確認所有物品能夠安全運輸抵達目的地。

*節（英語：knot）是一個速度單位，定義為每小時1海里，等於1.852km/h（海里的標準

Missions

Speaking of missions.. Here’s a more in depth look at them.

Airlift - transporting supplies or people by aircraft.

This can be split into two different types: strategic and tactical.

Strategic airlift involves moving people and supplies on routine trips across long distances.

Tactical airlift focuses on transporting the same things into a specific location accurately. 

任務

說到C-17任務，來近距離看看他吧！

空運物資 - 主要運送供給品或人。這可以被分為兩種模式：戰略上的及戰術上的。

戰略上的空運物資: 長距離的移動人或物資。

戰術上的空運物資: 專指於運送固定物品準確地送達特定位置。

Airdrop - sharing media between different apple devices, nope wrong airdrop!

This airdrop is actually a type of airlift.

C-17’s can drop supplies while still flying to troops or people in need of certain equipment or supplies.

This is used in humanitarian missions too for food and other helpful supplies.

隔空投送 - 你錯了！跟蘋果產品的Airdrop功能不一樣啦！

這個Airdrop是一種空中承載力。

C-17可以隔空投地物資至有需求之軍隊或團體，這同時也用於人道主義任務時，投遞食物和有用物資。

Aeromedical - C-17 to be a flying ambulance.

Flight nurses and technicians are in the plane and help wounded as if they were in a clinic.

空中醫療 - 這架配置空中救護機的C-17。

載著護士和技術士在機上幫助受傷的人宛如在準所醫院般。

不適用於武漢包機，這絕對會群聚感染。

Unfortunate Accident

On 28 July 2010 while practicing for an airshow in Elmendorf AFB, Alaska, a C-17 crashed killing all four members that were aboard. After the investigation, the safety board deemed pilot error was the cause of the mishap. Pilots and aircrew have a lot to pay attention to when operating an aircraft so it's easy to get overwhelmed. This is called task saturation and engineers are careful to make sure this doesn’t happen easily when designing airplanes. During the practice, the pilot made several dangerous maneuvers that exceeded the limits of the C-17. Because of this the airplane stalled at a height that was unrecoverable. Stalling happens when the wings of an airplane cannot produce the force of lift. I won’t get too much into the physics but the force of lift helps “lift” the aircraft and makes sure it doesn’t fall out of the sky. Unfortunately this is what happened. 

意外事故

2010年7月28日在阿拉斯加的埃爾門多夫空軍基地舉辦飛行表演演習，一架載有4人的C-17墜毀。經國家運輸安全調查委員會調查，機師的失誤被認為是造成此次飛安事件的悲劇。在飛行時，機上飛行人員在駕駛飛機時都需要有相當的專注力, 真的一個不注意就容易不知所措，意外隨即發生。這次事件發生被稱作是所謂的體能飽和，飛機在設計時，工程師會警慎的安全設計飛機，確保飛機本身不會體能操在並能降低意外的發生。在演習中，機師做了幾個危險的操作手法駕使這架飛機，造成機翼無法產生推力，使機身在高處失速，以致達到C-17所能負荷的最高上限。這邊不會多加以贅述物理概念，但特別強調這個推力是幫助“推使”這架飛機的靈魂關鍵耳使之在高空中取得平衡，不幸地是，發生在這架C-17及其機組人員。
