Some "theoratical" people came to me and challenged to build an aircraft measuring a maximum of 2 ft by 4 ft and 1 ft high, capable of carrying a 6 lb payload as well. I say this is a waste of time and money and I am out of the challenge but they say it is a small deal and are trying to organize a contest for it.

What do you think ?
Can you make a plane in a dimension of 2 ft by 4 ft ?
