This is exactly what i thought. Really cool build, but if you're going mil-spec, shouldn't you have chosen a more rugged-looking computer? With the macbook air it kind of reminds me of a Volkswagen on a jacked up monster truck chassis. My T61 would look badass in this, though.

Military Spec MacBook Air case. During use, it’s the external battery and power supply that are very well protected, not the computer itself. The MacBook Air is hardly a Toughbook (of course, a Toughbook is also 3 times as heavy).

I had trouble seeing where it actually houses the MacBook Air? In the first photo it looks like the battery and custom power-charging cable. There does not seem to be much clearance for the lid of the Pelican case if you put the MacBook on top.

It looks to me that the biggest cut-out is exactly the size of a 13" MBA. The computer also isn’t very deep, 0.4" on average.

there is a very slim slot above the battery and charger, that holds the closed laptop. When it's all close everything is quite well protected.
