I have an old post from SFO on a similar theme to this one, but I make the rules on this blog and this post isn’t violating any of them. (If you want to know what the rules are, let me know and I shall try and come up with some.) When I jet descends from altitude, the fuel the remains in the wing tanks will be very cold. The warmer and moister air lower down can result in the formation of ice on the underside of the wings where the remaining fuel is pooled. This Delta A330 shows that, as expected, there is fuel at the inboard end of the wings but also, less expected by me at least, there is a tank further outboard that still has fuel in it. I like the fact that fuel is kept further out since it alleviates bending loads. You can see the shape of the access panels where the ice is forming.

What Was Once a Tank
The new ferry terminal at Mukilteo is located on the site of what was once an Air Force fuel tank farm. There is not much left to give that role away anymore but the shape of the tanks is still visible on the ground. One of them still seems to have some of the old tank material left over too. Not sure what the story is with cleaning up the site and removing the material but it isn’t cordoned off so I guess it has been decontaminated.
Fire Truck Renovation
Aviation museums tend to be full of airframes of various types but sometimes they have associated items that they work on. The Museum of Flight restoration facility at Paine Field has a fire truck that they have rebuilt. It is tiny compared to current fire trucks but it is a great example of a truck from a time long gone and it is in great shape after all of the work put in to it. I thought I would share it here since it probably won’t get a lot of attention from everyone other than those that worked on it.
Gas Pumps
If you are going to have a museum to cars, why not include a tribute to the thing that makes them go? While fuel itself is not terribly suitable for an exhibit, the pumps that provide it prove to be a surprisingly good idea. Blackhawk Automotive Museum has a bunch of different gas pumps from through the years on display. They are all restored to pristine condition and probably look far better than they did when they were new.
The pumps cover a number of years and a variety of gas companies. The evolution of the pump designs is quite clear as you go through the years. I am not sure I fully understand how they worked but they seem to have involved filling up a clear vessel at the top of the pump with fuel. This filling process allowed you to work out exactly how much fuel was to be provided. Then, when the amount was worked out, the hose would allow you to drain the fuel down to the vehicle.
The early versions seem to be quite simple in layout and, as the years pass, the systems seem to become a bit more complex. A modern pump is way more complex but also severely lacking when it comes to styling. These old pumps look like they had some artists involved in styling them and the colors of the companies were similarly intricate. I guess that is how things worked in those days. Now efficiency, maintainability and functionality will win out over style.
