You really couldn't make it up I'm so glad I don't use the road for a living anymore. :-) |

Presumably nuclear submarines normally run without sonar operating - i.e., blind. How up to date are their underwater maps? What happened to Rule No 5? Look-out. Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision. |

They normally run with huge arrays of hydrophones, including towed arrays, connected to massive amounts of processing power to calculate the direction and distance of any object that makes a sound, by analysing the difference in time that the sounds reach each individual hydrophone. So must assume the object that the submarine collided with wasn't moving. So maybe their underwater maps are not up to date or precise enough. |

And whatever they hit didn't make an echo. |

And whatever they hit didn't make an echo.No active sonar, no echo. The major drawback with passive detection- if the object hasn't been mapped previously & isn't making any noise (or other objects in the area aren't making enough noise to reflect from that object), then you don't know it's there (unless it runs in to you, or you in to it).

Jesus. Played the clip numerous times until I could manage to confirm what I saw. Managed it after some playbacks. WTH was that muppet thinking of? He was clear of the barrier on the left so why reverse? |

What's going on in Staffordshire, period? Wedgwood railway station served the Wedgwood complex in Barlaston, Staffordshire, England. Although the station is not officially closed, no trains currently call at the station and it is instead served by a rail replacement bus.He's headed westwards, and has just passed the turning for a major complex. Maybe he was expected to deliver there, and - foolishly - thought it would be better to 'back' than 'turn'? |

Maybe he was expected to deliver there, and - foolishly - thought it would be better to 'back' than 'turn'?He saw the signs. Yep, passed the last turn, and finally the restrictions registered. At least he didn't snap the bridge in half. Reverse would have worked if a train wasn't coming. Likely a GPS fail. |

There's a purpose-built turning circle, and two sets of advance warning signs, before you reach the level crossing. |

I wondered what his destination was, so watched the video again to check his load. They look like mobile solar power lighting units. Checking the map again, one can safely assume that he was heading for Severn Trent water. If that was the case, there is only one way to get there & that is through Barlaston. Sadly there are many places like that & if one does deliveries in the country outside of major towns & cities, one will hit that same issue. One thing GPS cannot do is pre-plan, whereas the Mk 1 computer can. :-) |

I wondered what his destination was, so watched the video again to check his load. Still a GPS fail, its database should know the road isn't suitable and not offer it. It that means it says "no route" then that is what it says. At that point Mk 1 computers call the shipper and the customer and alternative delivery methods are arranged. If your GPS database doesn't know road restrictions, that is a Mk 1 computer failure (of the person specifying the GPS). On this side of the pond there are GPS that are truck route only aware which will keep you out of that trouble. OBW it isn't just out in the sticks, here in the heart of Los Angeles https://www.google.com/maps/@34.0941474,-118.2066013,79m/data=!3m1!1e3 look at that nice tight turn to get onto the south freeway. [look at a mirror image on the other side of the pond] I've personally seen several HGV's jackknife themselves trying to get on. Never mind the freeway is cars only and has been shown that way on the books since the 1950's. https://dot.ca.gov/-/media/dot-media/programs/traffic-operations/documents/trucks/truckmap-d07-a11y.pdf which leads to https://dot.ca.gov/programs/traffic-operations/legal-truck-access/restrict-list "No commercial vehicles over 6,000 lbs gross vehicle weight, including buses unless authorized by the PUC." and also https://dot.ca.gov/programs/traffic-operations/legal-truck-access/restrict-route-110 Mk1 eyeballs and computers need to be used before engine start! |

For those who wish to cry over idiots and supercars.It certainly is a case of ground effects stopping it from achieving orbit. What's a GPS? LOL Cheers. |
