It is always an experience to see these things flying. To my recollection, there were about 12,000 made, and by the end of the war, 3/4 of those had been either lost or damaged beyond repair. Most of the rest were trashed after the way.
OTOH, there are plenty of B-25's still flying. One of them (a bare metal glass-nosed model) used to cruise over all the time when I lived in Charlseton, SC. (And F-117's, F-16's, and A-10's as well, as we had an AFB there. I have never heard a more earth-shatteringly loud jet as the F-16! They would look about as big as a red ant in the sky, but it felt like they were strafing my apartment at 100 feet off the ground!)
