I Can See What You Were Trying To Do

But you messed up.

And that killed suspension of disbelief.

In the 3e GURPS supplement, "Funny New Guys" there are magic carpets.  It's an alt-history where magic exists and this supplement details that world's Vietnam.

The carpets the Army uses are: LUC-1, UC-23 and AC-05.

I can see where they were headed here.  H is the designation for rotary wing (helicopters) so change the H to a C for "carpet" and you're good!

Nope.

C means cargo.

And you don't double up.  This is why tankers get a K designation, T means trainer.

Besides, the designation system already has a code for lighter than air vehicles.  Z.

For Zeppelin.

So magic carpets should be LUZ-1, UZ-23 and RZ-5 (no preceding zeros!) and R instead of A because it's a recon carpet not an attack carpet.  This all assumes that they dumped the established blimp/dirigible numbers and started from 1 again.

And post MacNamara the 'L' would be changed to an 'O' making it the OZ-1.  And that's a lot more magical sounding, ain't it?
