Thanks for your patience during our recent outage at scalar.usc.edu. While Scalar content is loading normally now, saving is still slow, and Scalar's 'additional metadata' features have been disabled, which may interfere with features like timelines and maps that depend on metadata. This also means that saving a page or media item will remove its additional metadata. If this occurs, you can use the 'All versions' link at the bottom of the page to restore the earlier version. We are continuing to troubleshoot, and will provide further updates as needed. Note that this only affects Scalar projects at scalar.usc.edu, and not those hosted elsewhere.

The iconic landmark, which was closely associated with space exploration, was an ideal setting for marketing futuristic automobiles. The Bel-Air featured an advanced two-speed automatic transmission touted by the brochure, “The mighty ‘Blue-Flame 125’ engine teamed with Powerglide is the most powerful in Chevrolet history!” Interestingly, these early transmissions used a P-N-D-L-R sequence, which created safety problems. Drivers could easily overshoot the low gear and accidentally shift the car into reverse.
