16 B-25 bombers of the Doolittle raid launched from the aircraft carrier Hornet to give the Japanese something to think about.
I found this footage of the raiders taking off on what turned out to be a one-way flight for all sixteen aircraft, a consequence of having to launch early after the task force encountered (and sank) a Japanese picket.
Look at those aircraft barely getting off the deck with full power and full flaps, the ultimate "short field" take-off. B-25's weren't designed to operate off aircraft carriers. But that was ok, because aircraft carriers weren't designed to launch B-25 bombers, either. Thank God that we had visionaries, and brave men willing to try.
It took real men to make those flights. Fortunately America had no shortage of real men back then.
At the time though, it was a great morale booster for every American, and it caused the Japanese to recall some of their fleet to protect the home islands from another strike. This was the first time that the Japanese islands were bombed, and while it didn't cause much damage, it was far from the last time, and subsequent strikes hurt a lot more.
Thanks to drjim at Every Blade of Grass for reminding me, something that our media neglected to do.
