The Wright Brothers' almost childish faith that they could build a machine which would fly was the mainspring of their accomplishment.Without that, nothing could have happened.
We agnostics and atheists were sticking to the idea that self-sufficiency would solve our problems. When others showed us that God-sufficiency worked with them, we began to feel like those who had insisted the Wrights would never fly. We were seeing another kind of flight, a spiritual liberation from this world, people who rose above their problems.
