I am really impressed that we are able to fly safely at all if a tiny little piece of debris like this can cause plane crashes. Debris is a fact of life. Things fall apart, small pieces come off whatever substance or piece they were attached to. Are maintenance crews constantly just taking aircraft apart and vacuuming every surface they find?
Military aircraft are designed to be unstable, so that they can perform fast, odd combat maneuvers. The flight computers are the only think keeping those things flying.
Civilian aircraft are designed to be super stable.
