I've said this before but it's worth repeating from time to time.
I once worked for a company that makes baggage handling equipment.
You see, you've got this conveyor moving along at a fair lick and there's a bag every four feet along the conveyor. The problem is, to remove your bag and put it onto a different conveyor, the one that's going to your plane. The solution that these guys arrived at is a device that's euphemistically called a 'pusher'. It has a large paddle on it which 'pushes' your bag off the conveyor and onto the next one. Now they have to get this paddle to push the bag off and back out of the way again before the next bag arrives, remember the next bag is less than four feet away.
To do this the paddle has to move pretty fast, and it has to be able to move bags that can weigh 100 pounds or more. So it hits your precious Martin like a maniac with a sledge hammer and your guitar goes sailing into the air destined to overshoot the next conveyor. To stop the bag overshooting they put up a very heavy rubber curtain like those heavy weatherproof rubber doors that you see at airports. Your bag hits this curtain at high speed and drops onto the other conveyor.
The other scenrio is that your guitar in on the 'other' conveyor and the pusher lobs someone else's 100 pound of excess baggage in the air and it lands right on top of your guitar.
I offered to design a device that would match it's speed to the conveyor and carefully pick up the bags. But of course no one was interested.
