You got it! It is the Locheed R6V Constitution...(Constitution=Historical Document)
The Constitution was, and as far as I know still is, the biggest airplane to have used RATOs. It was designed for the Navy, and for Pan Am.
The main landing gear of the Constitution were spun up before landing, to approximately landing speed. Pilots complained that this made landings harder to accomplish.
The Constitution also had a double deck, which gave it a very distinct 8 cross-section. After Pan Am decided it was too big, and the Navy decided it was too costly, the 2 aircraft were sold on the private market. One went to Vegas and became a gigantic billboard for Alamo Gasoline, hence the 'Commercial'.
At a length of 156 1" and with a wingspan of 189' 1" it is definitely bigger than a Herky Bird.
