The old Mission impossible series had a self-destruct feature....This makes two....One in Iran, one over Seychelles....where is the "go home" default...
Modern yacht engines, even with a lost cylinder, lack of oil pressure, helm control,...there is a redundancy go home, safe mode or have a fail safe, and at least have our spook stealth drones self destruct....
Now we get laughed at and have Russians and Chinese techs crawl all over it....
