Well, since you clearly didn't play Halo 2, the bomb Chief rode out was operated on a timer. Since the time had almost expired, he used Cortana to stop the timer. In order to make sure the bomb blew up at the right time and that Cortana was not destroyed along with the bomb, Chief had to follow it. Besides, it looked cool.
I beat Halo 1 and 2, didn't take very long, except for that one area where I chased that stupid robot for hours through rooms that all looked the same and contained the exact same enemies. I always saw the blowing up of the bomb as an explosion on impact due to impact, even still, throwing the bomb out the hatch would have been less stupid and I wouldn't have gotten the feel like the character was just showing off so people would think he is cool.
If you actually controlled Master Chief as he launched himself into space, perhaps had to steer the bomb past the other ships, then it would be cool. The same reason grabbing someone and interrogating them in Splinter Cell makes the character badass, its the user's actions that define the character, not the cutscenes.
