Blackbird Flight Hours

After doing extensive research and obtaining information from Peter Merlin of NASA's Dryden Flight Research Center, the following flight hours are the most accurate of any current list. As for the missing aircraft flight hours, I am still waiting for this information to surface. Even though none of these aircraft have flown in awhile and probably will not, this list is accurate as of 21 May 2006.
