> 3. Is it really safe to fly around with in an airplane? Can major airlines help distribute these via standard flight routes to reduce cost?

These are too big for your standard air freight network or aircraft (that is, it's significantly larger then any typical ULD [Unit Load Device, shipping containers for airplanes]).

So it'll definitely be a charter to get one delivered. Weights going to be the big determinant in cost, dimensionally it looks like you could get it into anything bigger then a C-130. I doubt you'll be within the C-130s weight limits though.
