BRIGHAM CITY, Utah — Lightning forced Morton Thiokol Inc. to cancel a test of the space shuttle's booster rocket nozzle Friday, but the company said the delay will not affect plans for the first full-scale test-firing of a booster rocket on Wednesday.
Morton Thiokol spokesman Rocky Raab said the National Aeronautics and Space Administration had approved the Wednesday test, which will help engineers evaluate materials and concepts for a new shuttle rocket.
