Those few A-26s built (by ON-Mark? I think) are to me the ultimate version. The tip tanks for extended range, up-graded engines, the 8 -gun (Ma Deuce) nose, with 3 more M-2s inboard on each wing and more (3 I think) M-2s in the wings outboard of the engines, PLUS, 2 or 3 pods full of nastiness hanging under EACH of the wings on hardpoints! Whew!
I sure wouldn't want to be on the receiving end of a strafing run from one of THOSE!
And speaking of wingloads of nastiness, Litl Rooster, those Tweets could sure pack a wallop, too! The Air Force Museum in Dayton, Ohio has an A37 on display that has all the bells & whistles, and hangy-down goodies on it, plus the wing tip-tanks like you posted about. That is one cool plane! Did you ever manage to wrangle a ride? Cessna sure made/makes a good product! Most folks don't realize that the company that makes the rather common, high-wing private planes that are so commonly seen in the skies over America and elsewhere also made #1) a military jet trainer, and #2) that they modified those "cute, little pocket-sized" jet trainers into a pretty successful small, bad-a$$ed attack jet that could strafe, drop bombs and/or napalm, or shoot a high-performance jet out of the sky using Sidewinders! That's a lot of muscle rolled up and put into a tiny package!
