Overlords?
From experience I would say that there are many experienced aviation professionals in the Organization. Although what that really has to do with designing or managing the website, I am not sure.....
Lookingforajob - it has everything to do with it - access should be available for at least all of the major browsers and tested for MSIE essentially means that no consideration has been given to MAC users, who constitute a huge number of users. The plan should have been to make it as accessible as possible since it is critical SAFETY information.
I worked in eCommerce Marketing in the late 90's early 2000's and even at that point we were producing for multi-platform access which wasn't really that hard.
I am sure there are many experienced aviation professionals in the organisation but they need to expand their knowledge and skills if they are going to 'fly a desk' and operate websites (in my case, I was a Marketing professional not from a IT background but I still had to understand and be aware of the capabilities and the demands of the market).
Like I say, this is the 21st Century and they seem to be trailing far behind - remember what they tell you as a pilot 'fly the aeroplane, don't let it fly you!'
