DIADs were made in Israel for a while.
You are correct.
I said that II Morrow manufactured the first DIADS. They only designed them and did the prototype.
The Manufacturing was farmed out to a third party manufacturer under license of II Morrow.
Interesting fact. For the DIAD I, this manufacturer quoted $2400 per unit for the first UPS DIADS.
UPS gave the heads of this third party manufacturer a personal tour of the II Morrow facility.
Once they saw that UPS could manufacture the DIADS themselves, they reduced the price to $1800 per unit.
Deal done.
