the Red Top Cab company, I found nothing on the internet about it. Jeffrey reminded me the trailer was a Curtiss Aerocar, which I'd forgotten, though I've posted many in the past http://justacarguy.blogspot.com/search?q=aerocar and says Pan Am owned 4 of them, 12 passenger size... but he didn't remark on the Red Top Cab Co... so I don't know if that means this was a cab company that was or wasn't part of Pan Am
And that seems to be the Caribbean Clipper with PAA, the Pan American Airways system
this last photo looks like a Jack Vettriano painting
take another look at a Sikorsky S 40 to see how interesting the tail section and frame is
Dinner Key was originally an island in Biscayne Bay, which was connected to the mainland with fill in 1914.
In 1917, the Navy chose the site at Dinner Key to become the first continental Naval Air Station in the country. The base was commissioned the following year, and conducted flight training with 12 seaplanes and a single dirigible.
After the end of WW1, the Navy vacated Dinner Key, but the seaplane facility continued in operation by commercial operators. The New York, Rio and Buenos Aires Airline began service from Dinner Key in 1929. That airline was merged with Pan Am the following year. Pan Am operated an extensive route structure from Dinner Key in the 1930s.
in 1934 Pan Am put in an art deco passenger terminal
