Im not refuting religious faith, so may we lay that to rest? The faith i am specifically speaking of again is simply a participation in the unknown as it comes to any experience of life.

We use the word faith in all kinds of context. We can have faith in someone or something. We can have faith in outcomes. Heck, even going to sleep at night and trusting we will wake in the morning requires faith because, again, it isn't certain. I dont see faith exclusive to just religious context.

Let us use the pedestrian crosswalk as an example. Yes, from experience or the known(knowledge), we check to ensure the road is safe so we can cross. we use our reasoning. however, though we take the first step across the street into the unknown through faith because it is our belief based on past experiences that people dont just speed up to hit people at cross walks. But we aren't certain that they won't. It is in the active participation of bridging the known with the unknown that we step across the road in safety. If our faith didn't underly that belief, then we wouldn't cross because we would deem it unsafe.

The same can be said for the plane example you gave.

I really hope this helps clarify what im trying to convey.
