In a letter to the White House, Don Nelson, who served with Nasa for 36 years until he retired in 1999, wrote to President George W. Bush warning that his 'intervention' was necessary to 'prevent another catastrophic space shuttle accident'.
You know your right it just says fears raised last summer not written and its very vague on when a letter was received by the white house
And this guy retired in 1999 how fresh could he be on safety regs if they change daily like news reports say which still puts it back in nasa's lap.
