Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Airspace shopping experience:

1. Compare - without doubt the biggest advantage that the Airspace offers shoppers today is the ability to compare thousands of Airspace at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Airspace? Wrong! If the Airspace is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Airspace then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Airspace? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Airspace and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Airspace wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Airspace then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

Airspace means the portion of the atmosphere controlled by a particular country on top of its territory and territorial waters or, more generally, any specific three-dimensional portion of the atmosphere.

Airspace is divided into two basic types:

Controlled airspace exists where it is deemend necessary that air traffic control has some form of positive executive control over aircraft flying in that airspace.

Uncontrolled airspace is airspace in which air traffic control does not exert any executive authority, although it may act in an advisory manner.

Airspace may be further subdivided into a variety of areas and zones, including zones where there are either restrictions on flying activities or complete prohibition of flying activities.

By international law, the notion of a country's sovereign airspace corresponds with the maritime definition of territorial waters as being 12 miles out from a nation's coastline. Airspace not within any country's territorial limit is considered international, analogous to the "high seas" in maritime law. However, a country may, by international agreement, assume responsibility for controlling parts of international airspace, such as those over the oceans. For instance, the United States provides air traffic control services over a large part of the Pacific Ocean, even though the airspace is international.

There is no international agreement on the vertical extent of sovereign airspace (the boundary between outer space— which is not subject to national jurisdiction— and national airspace), with suggestions ranging from about 30 km (the extent of the highest aircraft and balloons) to about 160 km (the lowest extent of short-term stable orbits). In the United States, anyone who has flown above 50 miles (80 km) is considered an astronaut, and descending shuttles have flown closer than 80 km over other nations, such as Canada, without requesting permission first.
