I don't know that I would call this anniversary momentous, but 50 years ago today, the Tomorrowland Astro Jets attraction was renamed the Tomorrowland Jets.
Zooming in closer for this December 1963 shot, we get a look at the Spica, named after the brightest star in the constellation Virgo.

A July 1962 image:

The attraction's name was changed at the request of United Airlines, who had just taken over sponsorship of The Enchanted Tiki Room. As you can see in this April 1965 image, United cares. In fact, they give EXTRA care.

Seems that they cared that American Airlines' coast-to-coast "Astrojet" service was getting free advertising from Disneyland. Of course, the first thing you thought about when you got to Disneyland and rode the Astrojet was buying a ticket on American Airlines. It's only natural, you know.
