Occurred on February 14, 2023 / Tucson, Arizona, USA
: "I was driving east down I-10 to the Rita exit to drop off a friend who lived nearby after school, we noticed the traffic in front of us suddenly slow down and saw these wisps of orange colored vapor in the sky. Intrigued, I pulled out my phone and started recording the turned over semi truck oozing dark orange clouds from the trailer to show my parents the “weird accident I saw on the highway” It wasn’t until we got the shelter in place warning an hour later that we understood what we drove past."
