%26amp; puerto rico?|||No! If you show up with a Florida license they will excommunicate you! Because Florida is evil...|||No, you cannot. A driver's license is generally 3.5 by 2.25 inches. This is not enough area to supply enough lift to fly anywhere, regardless of it's configuration.
A fluid flowing past the surface of a body exerts a surface force on it. Lift is defined to be the component of this force that is perpendicular to the oncoming flow direction.[1] It contrasts with the drag force, which is defined to be the component of the surface force parallel to the flow direction.
Overview
If the fluid is air, the force is called an aerodynamic force. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag.[2] Aerodynamic lift is commonly associated with the wing of a fixed-wing aircraft, although lift is also generated by propellers; helicopter rotors; rudders, sails and keels on sailboats; hydrofoils; wings on auto racing cars; wind turbines and other streamlined objects. While common meanings of the word "lift" suggest that lift opposes gravity, lift can be in any direction. When an aircraft is flying straight and level (cruise) most[3] of the lift opposes gravity. However, when an aircraft is climbing, descending, or banking in a turn, for example, the lift is tilted with respect to the vertical.[4] Lift may also be entirely downwards in some aerobatic manoeuvres, or on the wing on a racing car. In this last case, the term downforce is often used. Lift may also be horizontal, for instance on a sail on a sailboat
Non-streamlined objects such as bluff bodies and plates (not parallel to the flow) may also generate lift when moving relative to the fluid. This lift may be steady, or it may oscillate due to vortex shedding. Interaction of the object's flexibility with the vortex shedding may enhance the effects of fluctuating lift and cause vortex-induced vibrations.[5]
Description of lift on an airfoil
There are several ways to explain how an airfoil generates lift. Some are more complicated or more mathematically rigorous than others; some have been shown to be incorrect.[6] This article will start with the simpler, more common explanations.
Newton's laws: Lift and the deflection of the flow
The cause of the aerodynamic lifting force is the downward acceleration of air by the airfoil
鈥?Klaus Weltner and Martin Ingelman-Sundberg [7]
Deflection
One way to explain lift is to observe the direct relationship between the lift force and the downward deflection of the air by the wing. John D. Anderson explains it as follows: "...the wing exerts a force on the air, pushing the flow downward. From Newton's third law, the equal and opposite reaction produces a lift."[8]
This explanation relies on the second and third of Newton's laws of motion: The net force on an object is equal to its rate of momentum change and To every action there is an equal and opposite reaction. [9]
This explanation of lift was used in the 1944 book Stick and Rudder by aviation writer Wolfgang Langewiesche: "鈥?the wing keeps the airplane up by pushing the air down."[10] Consequently, the lift is directly related to the deflection of the flow field behind the airfoil.|||Driver's license is fine.
Why would anyone assume that flights from Hawaii to the mainland are all international flights? It makes no sense to assume that.
And there are many direct flights from the US to various airports in Alaska. Minneapolis, Seattle, Detroit, San Francisco, Phoenix, Salt Lake City, among others all have direct flights to Anchorage and some to Juneau. In any case, if you had a connection in Canada, you would not leave the international transit area, so you would not need to show a passport.|||Great question, I was wondering the same thing myself. It seems you have a lot of answers saying you don't need a passport, but the thing about this that has always a problem for me it the fact that mostly likely any flight you take back from Hawaii will be an international flight and you will land at an international terminal, meaning customs. Can you just say, "No, no really, I am just coming back from Hawaii"? At this point in time, I don't even feel safe going to New Jersey without a passport.
ADDED: 'louisrichardk' I don't think the person asking this question is confused about Alaska or Hawaii being a part of the USA. If you flight to Alaska and you have to change planes in Canada, why would they let you back on a plane with out a passport? I believe that is the heart of this question.|||This sounds so funny to me. It's amazing that lots of people still think that Alaska %26amp; Hawaii are foreign to the US. Hawaii is the 50th State %26amp; Alaska is the 49th state so all you need is identification which your Florida license will do just fine. Even if you go to Puerto Rico you can use your Florida license for ID. as well, Nothing else is needed.|||Sure. Why not? You could even go to the US Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. They're all US territories.|||hawaii and alaska are part of the us so no visa needed... i'd assume PR is the same but i wouldn't know|||Better to use an aeroplane.|||you don't need a passport if that's what you're wondering.
