"The problem of flight is a problem of equilibrium."

"We have had considerable difficulty in getting the engine to work properly."

"It is not disputed that every person who is using this system today owes it to us and to us alone."

"The desire to fly is an idea handed down to us by our ancestors who, in their monotonous lives, looked enviously on the birds soaring freely through space, at full speed, on the wings of the wind."

"The difficulties were great, but our faith was greater."
