1.8 miles & 14 minutes

A supertanker can carry up to 300,000 tons of crude oil and at a maximum speed of 18 miles/hour, its inertia is so strong that it can still take 14 minutes and 1.8 miles to perform a "crash stop" maneuver (from "full ahead" to "full reverse").

I think of supertankers on days like this when I hear that Obama has finally taken the lead in superdelegates, and everyone knows now that Hillary Clinton won't win the Democratic nomination... but here we are, watching the shore approach only a half a mile away and knowing a crash will be coming very soon.

Prediction: Clinton will drop out of the race on June 15.
