8.   These devices squirt fuel into the engine exhaust to create quick extra thrust.

9.   Experts are predicting breathing disorders on epidemic scale unless engine exhaust and other industrial gasses are urgently controlled.

10.   NASA was adamant that the Soyuz could not dock at the station with Endeavour still there because it could hit the shuttle or contaminate it with engine exhaust.
