ADD EXTRA PADDING TO;
- NOSE
- TAIL
- RAIL opposite side to the handle on the rail...
Reason: the baggage handlers are human (obviously!

), and just throw it around like a big suit case... They pick it up at the "central handle", and throw it into its next position... So the nose or tail will get slammed into a wall, or the end of the container.... They also let it drop about 1 foot (30 centimeters), so the rail can also cop a pounding...
* Add the padding to those 3 areas, as a minimum...
