After an unmanned LM test flight AS-206, a crew would fly the first Block II CSM and LM in a dual mission known as AS-207/208, or AS-278 (each spacecraft would be launched on a separate Saturn IB.) The Block II crew positions were titled Commander (CDR) Command Module Pilot (CMP) and Lunar Module Pilot (LMP). The astronauts would begin wearing a new Apollo spacesuit, designed to accommodate lunar extravehicular activity (EVA). The traditional visor helmet was replaced with a clear 'fishbowl' type for greater visibility, and the lunar surface EVA suit would include a water-cooled undergarment.
How many people were on the test flight of the AS-206? What were the astronauts wearing during the dual mission AS-278? What was originally on the spacesuits prior to the clear 'fishbowl' helmet? What type of undergarment, if any, was included into the Apollo spacesuit? What did the LMP acronym stand for regarding the Block II launch positions?
