I'm an IT bod, and I have to do a fair bit of work on highly available systems, which often means physical separation of redundant components.
I've always been perplexed as to why many large jets only have a single MEC? Is there redundancy somewhere else in the plane? So much effort goes into making these systems super reliable and redundant, but then they are all put in the same room!
There was that incident with the galley water getting into a Qantas 747 MEC. Also the Qantas 747 gas bottle incident - what if that happened in a 777 (my favourite plane) where the pilots' oxygen bottles are in the MEC - and based on pictures, aimed at the electronics racks!
I'm wondering why they do it this way, just don't get it.
