I would have to say this: it works.
During Halo: Landfall, it is around 2-6:00 (depending on the date, idk) in the afternoon/evening. Remember, a space shuttle takes nearly a day to come down from space and land. MC was traveling at around Mach III. That means, it probably took around 12 hours to land. So, a timeline:
For 2-3 hours, MC is falling from space. He hits the atmosphere, and his armor locks up.
For another two hours, he is dropping through the stratosphere, and probably has lost consciousness. During his UNCONTROLLED FALL(because the Graphic Novel was low orbit and controlled), he is caught by the wind currents and tossed about for a bit.
Another hour/half-hour, he finally tears through the clouds and smashes into the ground. After a few hours, Johnson gets to him.
