Or the way we look at people who thought heavier than air flying objects are impossible by laws of physics.

Did any people actually think this? That would be weird, considering how we are surrounded by heavier-than-air flying animals.

"cannot be done" means "too difficult to be feasible" more often than it means "impossible by laws of physics"
