Convection Patterns in Boiling Water

This one is something I kept meaning to do on multiple occasions but never was ready when it occurred to me.  Boiling a pan of water, I am always fixated on the patterns that show up as shadows on the bottom of the pan as the heat affects the water by differing amounts resulting in convection flows across the pan.  This is the sort of thing that only oddballs like me find fascinating.  I finally thought to have the camera close to hand when boiling some water and got some footage of the patterns as they swirled.  I was quite pleasantly surprised that the lens didn’t steam up during this.  No doubt Nancy looked at me with that puzzled expression that has appeared many times after decades of knowing me!

A Turbo Mentor Seems Like a Nice Runabout

Beech built the Mentor trainer for the military with a piston engine before coming up with the more powerful turboprop version, the T-34C Turbo Mentor.  This saw extensive service with the US Navy.  Now there are plenty of them on the civil register including this one I saw one day departing from Paine Field.  The dark blue paint enhances the look of the plane and it looks like it has plenty of oomph.  I imagine it is a ton of fun to have.  I think it would be great to shoot air to air as well!

St Pancras Sculptures

While walking through the station at St Pancras, I realized that there are more sculptures than I had thought.  The one of Sir John Betjeman I knew of from previous visits, but the others were new to me.  I rather like the stark nature of their textures and imagery.  They have a rather aggressive feel to me which got my attention.  It’s nice that public spaces make the effort to add art to the functional areas.

Finally, I Catch the NASA DC-8

I have not done well in my previous efforts to photograph NASA’s DC-8 environmental sampling aircraft.  I had taken some distant overhead images when I was down at Star Wars Canyon and had hoped to see it fly at the air show at Edwards AFB last year.  Sadly, that didn’t happen as it was down for some maintenance issues.  With it due for retirement soon, I figured that might have been it.  However, I was chatting to some friends a while back and they informed me that it was due to come up to Everett for about ten days of flying in November.

This proved to be the case.  A program with Boeing as part of their EcoDemonstrator program had a new 737-10 that is ultimately destined for United (if the Max 10 ever gets certificated) flying with sustainable aviation fuel and the DC-8 flying behind it to sample the air, identify the emissions particles and measure the types of contrails formed but the different elements of the fuels.  The Max 10 was painted in a special livery which included the EcoDemonstrator Explorer program name.

The DC-8 was operating from Paine Field for the trials.  I was not able to get it arriving, but it was there long enough that I didn’t miss out.  These shots are from the first time I was able to see it getting ready to fly and heading out.  Over the course of the time it was here, I had further encounters and some of those are worthy of their own posts.  Consequently, there will be more to share of this fantastic relic of a bygone era in passenger aviation.

Leopards Are Harder to Find

Our time in Kenya and Tanzania included plenty of lions but, when it came to the next big cat on the food chain, things were a lot less common.  The leopards were there to be seen but they were not anywhere near as numerous.  It doesn’t help that, unlike the lions that live in large prides, the leopards have a solitary existence.  If you are in a territory, it is one leopard that you are looking for.

We did have some encounters, though.  The first leopard we came across was at the beginning of the day as we headed out from the hotel.  We hadn’t got very far when our guide spotted a leopard sitting on a termite mound.  We stopped and got some shots of it and then tried to get closer but leopards are a lot more skittish than other cats and it didn’t take much to spook this one.  It ran off up the hills.

Our next encounter was with one that had been busy feeding.  On a couple of occasions, we had seen carcasses of animals up in trees where the leopard had pulled them.  In this case, the leopard had then taken to another tree to rest after its meal.  We were quite close beneath it, but it didn’t seem bothered about us and I don’t think it was likely to pounce down on us.  Instead, it was sleeping and barely recognizing our presence.

The other encounters we had were probably with the same leopard but this time down in some bushes alongside a river.  The first time the leopard was pretty well in the bushes and was lying down.  It didn’t seem intent on doing much and we left it after a short while.  Back in the same area on another day, it was on the move.  We were able to be ahead of it and it walked towards us before cutting back into the bushes and being lost from sight again.

The leopards are such powerful creatures, and they look far more menacing than, say, the cheetahs.  Their ability to haul a heavy animal up into a tree is impressive and, pound for pound, they are stronger than the lions.  However, the lions will still take them out if given the chance.  With overlapping territories, this is not something to be ruled out.  I’m glad we got the time with them that we did.

Drake is in Town, But Not at a Good Time

Drake recently announced he was stepping back from touring, but this comes after he has been on quite a touring schedule.  Seattle was one stop he made.  He has his own 767-200 that is operated by Cargojet for him.  It is painted in a distinctive sky-blue livery.  It came into Boeing Field for the duration of his stay in the city.  Sadly, his schedule means he finishes a show and jumps on the plane to fly to the next location overnight.  That meant it arrive some time after midnight and departed at an inconvenient time too.  I only got it while parked and the light was not great either.  Still…

Getting Down to the Level of Fungi

Ever since I have had cameras with flip out screens, I have been far more likely to get down to the right level for a photo.  Lying on the ground was something I would only do in the right circumstances.  Walking through the arboretum with Nancy is not the right time to get grubby doing that.  However, now I can let the camera be low down and check the shots from a slightly more comfortable height.  This was the right thing to do when I was taking some shots of some mushrooms.  You get a totally different perspective from ground level!

Frontier’s Weaselly Pun

Frontier Airlines names all of its planes and the names reflect the wildlife artwork on the fin.  One of their A321neos was taxiing out at Portland one morning.  It had some sort of weasel-like creature on the fin and the name of the plane was Kari the Fisher.  I certainly get the Star Wars reference but I had to look up Fishers to find out that they are a member of the weasel family.  I had never heard of them before.  Nice to think that my enthusiasm for aviation can be educational in other spheres!

Memorial to the Wrens

Walking through the old parts of the city of Portsmouth took us by the cathedral.  In the grounds there was a memorial to the Women’s Royal Naval Service.  Known more commonly as the Wrens, this was the branch of the Navy for the women before everything became more integrated.  The top of the memorial is the various types of hats that Wrens wore in service.  My gran was a Wren in the war and made friends in the service that stayed with her for the rest of her life.  She would go to many reunions.

Components for 767 Production

One of the reasons we get a stream of unusual freighters into Paine Field is the delivery of sections of fuselage for the production lines.  This can include front fuselage sections, center wing boxes and empennage elements.  One afternoon an Antonov showed up to deliver some of these parts.  While getting the plane arriving was why I was there, it was interesting to see these chunks of future planes (I believe these were for the 767/KC-46 line) being offloaded and driven off to be used.
