Basics - 2 - What is an aeroplane ?

What is an aeroplane ?
" A heavier than air flying machine, supported by aerofoils, designed to obtain, when driven through the air at an angle inclined to the direction of motion, a reaction from the air approximately at right angles to their surfaces."
Difficult to understand, don't worry we will keep it simple.

" All man made contrivances which fly, that is to say which are kept in the air by forces produced by the air, are called aircraft".
