One of the few aircraft to fly in three wars - WWII, Korea and Vietnam - the Douglas A-26 / B-26 Invader gained fame as a light bomber. Designed by
engineer Ed Heinemann, the XA-26 prototype first flew in 1942 and flew combat missions beginning in June of 1944. Two versions were produced: a heavily-armed solid nose "B" model and a glass nose "C" model for precision high
altitude bombing. More than 2400 were built, serving with distinction in both the Pacific and European Theaters. Redesignated the B-26 (not to be confused with the B-26 Marauder), Invaders saw combat in Korea and are...

Developments of Americas first heavy lift space rocket Saturn I, the Saturn IB and Saturn V propelled Americas space program during the Apollo and Skylab eras. First launched in 1966, Saturn IB replaced the Saturn Is S-IV second stage with the more powerful S-IVB. It could carry a partially fueled Apollo Command / Service Module or fully fueled Lunar Module into low Earth orbit, allowing critical testing of these systems to be conducted long before the Saturn V was ready. It also flew one orbital mission without a payload, with the extra fuel used to demonstrate that the S-IVBs J-2 engine...
