Back home in Underwood, Maryland, however, his uncle Hiram F. Jenkins, owner and editor of the local newspaper, refuses to print the story. Nicholas quits and continues to work on his own airplane, with the devoted help of his little daughter Peggy. Peggy is actually the first in her family to fly when her friends, Patrick Falconer and Scott Barnes, induce her to get inside a large kite they have made, and run with it in a field until she is airborne. The kite is caught in a tree, however, and Peggy gets a black eye. Later, Nicholas dies when his experimental airplane crashes, leaving his wife and children alone. By Peggy's adulthood, planes are capable of flying at an altitude of 11,000 feet, and speeds of nearly 100 m.p.h.
