Traveling across the world? lol or even in the same country
In WWII an airplane would be useful to bomb the other countries.
To rescue people from a sinking boat
Mainly for long distance travel and fuel efficiency.
They are useful for takeoff to get lift and at landing for slowing down the plane.
Flaps would increase drag increasing your speed will increase it even more
I think that's airplane traffic updates are very useful. It has helped me alot when i was going on holiday.
because u would die usually so u will die more painfully this way
I don't know if I would use it in a car, but on a boat, or an airplane, it seems as though it would be useful. I think a laptop is a bit much for a car ride, but I hear they are pretty accurate and keep good GPS locks for the whole trip.
On an airplane.
An airplane, because it starts with a vowel sound. (In the UK you would say an aeroplane.)
With airplane... There are 2 airports that are useful for the goal: Paphos and Larnaca.
Those seagulls would weigh two pounds whether they were sitting in the airplane or flying in it. This is because they have push the air below them (in the airplane) down with two pounds of force to keep two pounds in the air. So, yes, the seagulls would add 2000 pounds to the airplane's weight.
