re: NASA has removed Shuttle engineer, a former shuttle astronaut, after he expressed concern for Shuttle flight.
Not exactly.
Take several deep breaths and wait until the story clarifies.
Maybe we're witnessing the birth of another 'political urban legend',
like the false story of the general who was forced into retirement
after telling Rummy that more troops were needed for the Iraq
invasion. It's amazing how so many otherwise rationale people
will eagerly swallow any fable that happens to make them 'feel good'.
