He escaped in a Pelican with a few others. Read halo book "The Flood".(ignore the legendary ending its just a funny easter egg) Sargent Johnson along with 2 marines and an officer escape aboard a pelican but have to power down due to covenant still within the area,or so they think. The master chief manages to find a 3 link cryo capsule that was ejected from the pillar of autum before crash landing, the contents of this pod were 2 dead soldiers and a spartan II. Once the chief reached the pelican he meets the 4 crew, an egotistic officer, a marine, sgt Johnson, and their pilot. According to the book MasterChief didnt believe Johnson when he said that the flood ignored him and doubted him for a long duration of the trip. Later in the book when they meet Halsey the Chief askes why seargent Johnson was alive. Halsey respondes with "sergeant Johnson is rare with his case. suffering from plasma poisoning which would kill most men. It seems to change the DNA within the body without harming it besides death. The flood has a nearly infinite amount of RNA within the bodymass(RNA is basically half of the strand of DNA used for making the blueprints to your body for those who dont know). Johnson's RNA was so randomized that the flood couldn't match his RNA with anything so it ignored him. The plasma poisoning he had was from prolonged combat with covenant. Almost all men have died from this, him being the obvious exception. Also being part of the spartan program but not becoming a full spartan was also on his side."(these werent in correct order of what she said but it is what she said) . There is also a comic all about him specifically after what happened when jenkins died.1337 haxHe escaped via Pelican dropship along with Warrant Officer Polaski, an ODST Corporal by the name of Locklear, and an ONI Lieutenant named Elias Haverson.Plot...IDK read first strikeon a pelican read first strike
Lieutenant McCay sacrificed herself and the captured Covenant CCS-Class vessel the Truth and Reconcilliation to stop the Flood from reaching Earth. At some point Johnson and the afformentioned people were on a Pelican before the ships destruction.
the real way johnson got off the pillar of autumn
f you finished halo 1 on legendary, you will see Johnson hugging the elite, then see both of the get engulfed in the explosion of the pillar of autumn and died. What really happened was just when the pillar of autumn exploded, Johnson hugged the elite, but what he really did was he hid behind the elite The elite was exposed to 1,000,000 degrees of super heated fire, 50 times hotter than the sun. The elite burned into a crisp in a matter of seconds, while Johnson survived by hiding behind the disintegrated elite body. With halo gone, Johnson was floating in space. Just as the elite got burned by the explosion, Johnson took the elites helmet, and enabled him to breathe in outer space. How he got back to earth was he saw a body of a grunt in space drifting nearby so he grabbed the gas mask of the grunt to propel Johnson towards earth at 300,000 km per second, as fast as speed of light.
