I worked briefly in a very small Vermont Fed Ex package center. I worked evenings unloading trucks for outbound shipment, not as a morning load the trucks for delivery guy.
I'll admit that 3 times is VERY suspicious, and I hold no great loyalty to Fed Ex, but there are lots of reasons that packages go astray even up here in tiny little Vermont.
Given the volume of packages coming through even up here for the holidays and the amount of time I as a 'box monkey' had to deal with each one , I dont think that it is very likely that someone in the warehouse, saw your box, said 'ah-ha, this is the new Panther from Cyber hobby, I'll take this.'
Jewelry manufacturers, small electronics, liquor, adult material maybe. But the folks I worked with would not know a model box from a box of swimsuit models.
From the inside, Fed Ex takes package theft very seriouslly, there are cameras everywhere and employees do not get to bring backpacks or bags of any type into the package handling area.
Fed Ex says it prosecutes vigorouslly and there is a $5000 reward for ratting someone out who is stealing.
The crew I worked with was tight and had been together for a while (like the 'old hands being there 6+months) , but this is not a high paying job and no one on the crew would pass up $5K for anyone else.
The drivers have more time with the packages, but all packages are scanned onto the trucks, so the drivers are responsible for each package. Even our trucks up here are alarmed and the drivers wear a RF wristband that unlocks the back of the truck.
On the other hand, the inside of a fed ex processing facility is organized insanity, run at high speed. Packages are supposed to fill every meter of the converor belt, and the belts never stop. Everything is 'supposed' to be scanned, and scan rates of af 99%+ are the norm, but when you're loading 750+ packages per hour into a trailer..
It is possible your box got loaded onto the wrong truck, came back, got set aside, and has not been 'found' yet.
I hope that's the case.
I sure hope your kits turn up
I know this is no consolation, but I hope a little info on the inner working of Fed Ex helps.
