The investigation of the 2003 space shuttle Columbia disaster was budgeted $50 million, based in part on the cost of the investigation into the 1986 Challenger disaster.
What was the initial budget for the 9/11 Commission, which investigated the most severe terrorist attack ever on the United States?
Next-day ANSWER: While 39% said $15 million, 35% (Perhaps test-wise people gaming me? But it is public information...) said $3 million. The answer is $3 million. Through two subsequent increases, it went to $15 million total. Bush opposed the creation of any such commission. It's interesting that the investigation of a shuttle disaster involving primarily one agency merits a $50 million budget, but a multi-agency, multi-national investigation involving the deaths of thousands of people and with profound security implications merits $3 million.
