There's been quite a stir on X as some users speculate that a NOTAM, or aviation notice to airmen, suggests a potential Russian Navy hypersonic missile test off the coast of Southern California. However, that's not the case. According to The War Zone, the NOTAM is actually in anticipation of a Russian space booster splashing down in the Pacific. 

Let's begin with the misguided hype on X about the threats of Russian missile testing off the California coast. These posts collectively have generated more than a million views. 

Meanwhile, two US defense officials told TWZ the NOTAM is in place through May 26 because of the re-entry of a "Russian space launch booster." 

"It is not for a launch or a military exercise," the officials said, commenting on the social media hype.
