Whilst it is certainly a shame that a nice model (and expensive) got destroyed, my own view is that it wasn't packed properly.

I will justify my opinion thus;

an hour ago I got off a plane, an hour long flight and I nearly lost my lunch... very bumpy with turbulence. (the video mentioned airfreight..)

Now as the video shows, firstly the model has escaped from its strapping - so it wasn't fastened to the base itself, just resting on it. After that happened then the result is a forgone conclusion, it will rattle around and do the rest.

Applying straps front and back either side of a base appears to either, allowed model to move or applied a bending moment (pressure) the the hull so inevitable it broke it's back with a bit (or a lot) of vibration.

If the opening of the box is "live" as suggested then the package wasn't damaged was it? Yet the model is loose and broken. Certainly heart-breaking for both client and model maker, however, personally I don't see it as a clear cut case of the courier's fault.  :-\

I'm going to add that a couple of wonky arrows and fragile written on by hand in thin black marker isn't going to be taken seriously either. Stickers, stencilled or printed and taped on would be an improvement.

I'm not suggesting blame for either party and I don't live in a country where FedEx operates so do not have a bias either way, just as I said, an opinion.
