Walk up to the rocket and you can read the phrase "Swallow This!" on it. You do not have to worry about being too close to it.

Lose flying after Redeemer explosion
When you do enable the fly code, if you are ready to use the human-controlled Redeemer, make sure you are on solid ground and that you can not be attacked. As soon as the Redeemer missile explodes, you will be caught without flight. For example, one of the tall towers in Plunge will make a good perch because no one can attack you there.
