When pressed in New York about his decision to forego a radio, Lindbergh said, “When the weather is bad you can’t make contact with the ground.
When the weather isn’t bad a pilot doesn’t need a radio.” Lindbergh had already lost his patience with the incessant and sensationalistic press.
To make matters worse, he had not yet become technically eligible for the Orteig Prize, which stipulated that 60 days must elapse between acceptance of his entry papers and take-off of the flight to qualify.
His St. Louis backers told him to fly when he was ready, despite the Prize.
