Waiting for the Whump

Your plane is slicing towards the runway. The buildings and street lamps keep getting bigger and bigger. You can see the tarmac below you. The plane swoops down gradually nearing land, and you can clearly see the grass along the runway. Now, isn’t there a slight shrug, as you brace yourself for the whump and the slight jerk that accompanies the touchdown? Those few seconds, as you are wondering “has he touched down already? Was it so smooth?”

There should be a name for that state of mind.

Also encountered when you have lit the fuse of a fire-cracker, and are waiting for it to explode. Or when you notice a bump/pothole in the road too late for you to change course.
