I'm having no luck downloading those files. Could someone please post the two PDFs themselves?
At the time of the AS-204 fire, the next scheduled manned Apollo launch was planned for the summer of 1967. After Grissom White and Chaffee successfully flew Apollo 1, LM-1 was scheduled to fly on Saturn 206. The Apollo 258 mission was scheduled to be flown by the eventual Apollo 9 crew. On day 1, LM-2 would be launched on Saturn 208 and then the next day, the first Block 2 Apollo CSM would be launched to rendezvous and dock with LM-2 The first Block 2 would be launched on Saturn 205. THe flown mission would be similar to Apollo 9 but since the mission involved dual launches of Saturn 1Bs a reduced propellant load would be carried on the Block 2 CSM. I'm pretty sure a Saturn 1B could launch a fully fueled LM, but I'm not sure if that was the plan for this mission. Apollo 258 was a convenient abbreviation for an Apollo flight that included dual Saturn 1B launchers (205, 208)
Amongst the other documents that seem to have been removed from the NTRS are a pair of documents that comprise the first two volumes of a 'Reference Trajectory' for the unflown 'High Earth Orbit' LM test mission that was cancelled due to LM production delays.This report which dates from the start of 1967 covers a version of the mission where two high Earth orbits are followed by two low Earth Orbits, the 'mission profile evaluation' section of volume one (attached) notes that this scheme had been superceded with a profile featuring four high Earth Orbits due to crew workload issues. Research is continuing to see if information on this later version can be located.https://app.box.com/s/3wsod1of7jj1wku711ddyghrw27sgv5d
