Fun fact: There is very little need for sound proofing a mech cockpit if its intended for space. So this would probably be the first time Halim would have had to dealt with the noise of his own guns...if the mechanoids hadn't basically deafened him for the duration of this fight. 

Also, I hope Volana has time between her life and death struggle to appreciates his /awful/ piloting on the surface. 

Tldr: The baby is having a bad time and wants to go back to space.
