B-29's and P-51's Over Japan They sure paved the way for us to experience (and live) the freedoms that we certainly would not have were it not for them...regrettably, so many of today's generations have so little -- or no -- awareness of the fragility (and cost and blessings) of freedom.  This WWII video is 36 minutes long and the documentary follows a B-29 mission over Japan.  This is live footage of the 3,000 mile round trip air assault upon the Japanese mainland, with 3 bomber wings and a host of P-51's.  A great compilation of combat footage from WWII.  For those who would like to trace the dots from Pearl Harbor in 1941 back to Japan in 1945 -- the Last Bomb.
