Wow, missed this the first time around. I was having a little trouble relating to the Spitfire size comparison- "well yes, of course it quite a bit bigger..."- and then I scrolled down more to see it next to the KC-10. Goodness, it IS a big airframe! Having just a wee bit of experience with vacs (and an unrealistic number of potential future experiences in my stash) I found myself thinking, "Heck, just the flap-fairing "canoes" looks like enough of a pain in the neck (and eyes)!"
Well done, and I shall studiously avoid hunting up information about Titan Models, lest I be tempted by something hardly justifiable. Well, maybe one quick look wouldn't be too dangerous...
