[QCWA] History Questions

[Don W7WLL]

Two questions:
1. In the early 50's perhaps a bit before, did the FCC not reserve some of the lower W suffix calls for the military such as MARS stations??  I was CHOP of K7WAI in that era and I seem to remember a lot of other MARS amateur calls all beginning with the W suffix.
2. There was a statement made by a local ham that  Z two letter calls were reserved at some point in time for traffic handlers. I think that is balderdash, that the FCC never reserved calls for any personal reason.

Anyone know?
