On the heels of the Fairchild XC-120 Packplane http://www.secretprojects.co.uk/forum/index.php/topic,6263.0.htm, let me present it's little British cousin, the Miles M.68 Boxcar. Basically a four-engined variant of the M.57 Aerovan, the one and only M.68 Boxcar had a removable central fuselage which could be towed on it's own wheels. It would have been quite handy, I think, to have fuselages kitted out for cargo use, refrigeration, passengers, medevac, you name it, to switch out as needed.
Here are some specs and pics, all from Don L. Brown's fantastic MILES AIRCRAFT SINCE 1925.
