Not sure if this has been discussed before, so apologies if this is old hat.
Why are there flamethrowers in this movie...?
I can understand the hand weapons, but why after the storm are there people going around with flamethrowers? Are they using them to sterilize the cargo bay, in which case are they are of some biological contamination then, and really don't they have something better than a flamethrower to use?
And if you're going to knock off an infected crew member, why not just shoot them and bury the body rather than set fire to it and have smoke and ash (which might also be contaminated) blow into your cargo bay?
Or, is is just a nod to the flamethrowers in the Alien movies?
