# The value of a paper plane
A paper plane can model a real plane, with limited resources and with
relative ease. Paper has a weight to strength ratio similar to
aluminium which real planes are made of.
During the Great Depression, designers used paper models to help
design planes that were later used very effectively by the Nazis in
World War Two.
# Initial designs
Try to fold a paper plane and throw it. See who's can fly well. Think
about why certain designs might fly better.
# The classic design
{ width=50% }
# A different design
John Collins designed the current world record plane for distance.
(Optional) Watch the world record throw: <https://www.youtube.com/watch?v=cXqwUxkNXVE>
Folding the record plane(starts itself at 2:50, watch as much as you
want)

# Extension: more designs
Check out <https://www.foldnfly.com>, the instructions are not perfect
but there are quite a few planes.
The loop plane is pretty good
