In Remembrance 2023
A buddy of mine recently asked me about the "ZL-4" designation that is often found on post-war L-4 manuals. I didn't know and it wasn't the first time I had been asked. So I decided to start looking again. The only thing I found was that the Z designation was for Navy LTA "Blimp" aircraft. Not really comparable for a Cub unless you're talking about speed. So I remembered another buddy from my Air and Space Museum days who was the Research Librarian and is now the Curator at Seattle Museum of Flight. I figured of anyone would know, he would.
"The Z prefix was actually used more often than most observers realize, and was available for assignment as a prefix for Obsolete aircraft (still in the inventory and often still active) between 1928 and 1962, when it was finally dropped with the tri-service redesign of the designation systems."
