The program looks similar to the Soviet N1 program, in scale, testing and failures. Korolyov was in hurry to get to the moon, and tried to assemble everything and test in actual flight. After 4 failed test flights, the program was scrapped.
This approach had worked with the R7 rocket (the Sputnik and Gagarin's booster, predecessor of Soyuz). But at this larger scale, it seems things break apart much easier if not properly tested in parts.
