A few years ago, I had the pleasure of flying a Yak-52 from the rear cockpit. Nice, snappy plane BTW 
When we started the engine, a 360 hp 9-cylinder radial turning a paddle bladed 2 blade prop, the whole plane shuddered so bad when idling that ... "now I see clearly, now everything is blurry, now I see clearly, now everthing is blurry again". Turns out that my eyeballs actually where shaking in their sockets
hock: Took a bit of getting used to during line up.
