Its reaally simple guys, there's an engine on the tail, so its design makes it tail heavy orientated, when you off/on load the thing you secure the nose and use anti tipping off/onload procedures, if you can't secure the nose gear you use anti tipping off/onload procedures with extreme caution!, the ball mat at the back end gives you the abbility to offload the back end up the left hand stick, and if its a through flight any offload should be planned on the left side. look at the picture, no broken tie down strap dangling from the nose that I can see, no fuel panel open, the only thing I can't see is if the main cargo door is open or if the rear belly door is open, but you can see the fwd belly door open,
the 727 has a tail post, and I can't count the number of times I have seen a 727 taking a rest on the tail post.
A rear main deck cargo door would be too difficult due to the sweep of the wings, a special loader to go in at an extreme angle, and very difficult access for tugs and dollies.
but saying that they are always entertaining photos and i'm always glad it didn't happen to me, its all down to procedures and load planning, particularily for downline stations when its only a partial off/onload , apart from that a great freighter, one of my favourites next to the dc10-30, makes the 747 seem too easy.
