On its way back to base, the US Navy MQ-4C Triton reconnaissance drone that had been patrolling the Strait of Hormuz took a turn towards Iran, squawked code 7700 (general emergency), and started descending, falling off ADS-B as it dropped under 10k feet.…..
It has now been an hour, and the drone has not reappeared on any ADS-B feed, either @flightradar24 or @ADSBex.

As someone says in the comments:
“Some Saudi Patriot operator just lost his job”…..
