I recall standing on the Bridge when a vessel of the Gray Funnel Line dropped Anchor off Hong Kong.....along with every inch of the chain attached thereto......after all of the racket...smoke and dust settled and a very prolonged silence by all present.....the XO was heard to say...."Gee....That went well!".
Fortunately a Fleet Tug was in port and was able to retrieve it all within a few days.
