"We have at last succeeded in making a machine that will fly."

"We are not content to walk upon the ground."

"It is difficult to understand how anyone could have been so blind to the truth."

"I confess that in 1901 I said to my brother Orville that man would not fly for 50 years. Ever since I have distrusted myself and trusted him."

"We have been making flights at an altitude of about 50 feet."
