GPS wouldn't work if relativity was wrong. Radio wouldn't work if our theory of electromagnetism was wrong. Satellites wouldn't stay in orbit if Newton was wrong. Modern medicine wouldn't work if our understanding of biology was wrong. And chemistry, physics, astronomy, mathematics and so forth all overlap, all require each other to some degree... and each of these interconnected areas of knowledge need to be correct, because we want to use it to build things or solve problems or make discoveries.
That's why I like science and engineering, it's a whole structure that, while not perfect or complete, has self-reinforcement and self-correction built in. And if it's right about something, the proof will be in the pudding. Otherwise, like you say, your airplane will fall out of the sky.
