@Knowledgepoint I'm speculating that these vaults might originally have been built as coal cellars for the houses, perhaps with a "coal-hole" manhole in the pavement so deliveries could be made without disturbing the occupants of the house.
@FlipLondonTours Interesting that a really significant number of men kn this shot are not wearing hats. I know that change started after WWI, but was the music world leading the trend?
@iamwizardofash@EvanAboutCinema When I worked there at end of the 1970s the roundabout was just a big open space with stairs down to the circulating area, and you could look across and see the exit you wanted. Then they built the Imax in the middle and turned it into an underground maze.
An outbreak of intense and titanic thunderstorm cells is underway across a heat-besieged Western Europe, with more than ~15 lightning strikes occurring every second in the strongest storm cores and convective cloud tops chilling down to -68 C (-90 F).
The cities of Paris, France and Amsterdam, Netherlands just simultaneously experienced several hours of frenetic lightning activity and heavy rainfall. Now, the original cell that formed over Paris has passed through Belgium and is fast approaching Amsterdam with yet another wall of fierce, electrical convection.
@cook6_cook@SimonCalder Sorry for squashed words, was trying to get it all in the word limit for one post. Even if the skies are clear now, the chaos caused by planes & staff in wrong places & beyond allowed time on duty takes time sort and still caused by that weather event.
@cook6_cook@SimonCalder Lightning app,last https://t.co/XQT0Uu5Zo0 dots=lightng strikes prev 20min,circles with number= 2many to show with dots.Storms over us Fri/Sat night then wandered up coast to Amsterdam,blocked many air routes.+storms N France blockd other routes,planes wrong places,days 2sort out
@Tweets2any1@flightradar24 That's true, but the problems aren't caused by storms at the airports. Passenger planes have to follow set routes and can't fly through thunderstorms. A series of storms have been passing across the North Sea and northern Europe, blocking all routes through the area at times.
@Knowledgepoint They also used a small red lamp for the same purpose (still used today in Australia), which is why Sir A Conan Doyle titled a book of medical practice stories "Around the Red Lamp". This may be a surviving example, in Brighton Rd, South Croydon.
@SteveWhiteRail One of the things I hope the report will address is whether a collision between a square-ended cab and a pointed nosecone concentrated the impact on a much smaller area, and whether it might have been survivable if both trains had been of the same design.
