If You Want Shocks, You Don’t Need Fast Jets

Every once in a while, when photographing a fast jet at transonic speeds, you might get something in the background that allows the diffraction caused by the formation of shockwaves to be visualized.  I have posted about that here.  I was in Vancouver and shooting the floatplanes taking off from the harbor (since it is a Canadian harbor, perhaps I should write harbour).  As I was looking through the images zoomed in to check on sharpness, I realized that there was a visual effect of a similar nature.  (If you think this is a Schlieren effect, it is not.  That is a technique that involves a certain type of lighting to show the density differences but should not be applied to every time you see it in the wild.)

I don’t know whether what is showing up is the result of shocks forming on the props as they spin rapidly or just the tip vortices causing a similar effect.  You can often see diffraction in trailing vortices.  Whatever the reason, as you look above the aircraft at the patterns of structures on the shoreline beyond, you can clearly see some interesting effects.  Since the props are spinning fast and there is an overlap of the wakes from each pass of a blade, the shapes are rather complex.  Now I know that this is a thing, I might be tempted to take a longer lens and see what I can get in more detail of this interesting visual effect.

A Primer 747 Really Catches the Sun

A primer finish on a jet looks a lot more dramatic in sunny conditions.  The green finish of the protective film is quite reflective so the sun really makes the plane shine.  This 747-8F freighter was carrying out some production test flying from Everett during a visit.  I was getting ready to leave when it came in so I got a bunch of shots.  As I was driving away, I heard the sound of a jet and it turned out the plane had landed, turned around and taken off in the opposite direction.

I was a bit annoyed as I saw it climb and turn pretty sharply – I assume it was lightly loaded.  Then it became apparent it was going to make a teardrop turn and come back in to land again.  Since I was now on the road home, I pulled off into a parking lot somewhere close to the line of the approach path and got the camera back out.  Into view it came and flew across right ahead of me.  I got a few extra shots.  Not the dramatic climbing turn but still a nice to have addition.

Return to Evergreen

I have made one previous visit to the Evergreen Aviation Museum in McMinnville Oregon.  That was probably ten years ago.  I was in Portland for the morning Open House at the ANG unit so, having gone that far, I decided to go to the museum to see what had changed.  I underestimated a couple of things.  One, McMinnville is a bit further from Portland than I thought it was so it took about an hour to get there and that hour was also going to be added to my return journey.  Also, a lot of things have changed so I was going to spend more time there than I thought.  I was not getting home early that evening!

When I last went, one building housed the exhibits and a second was being built.  It was close to completion and they were talking of space exhibits and, hopefully, a Space Shuttle.  That didn’t work out but now there is certainly a lot more to see.  There are two main exhibition buildings – pre-Vietnam and post-Vietnam eras – housing civilian and military exhibits.  There is also a theater building.  None of this includes the water park that is close by.

The amount of space means that the exhibits are not crammed upon each other although some areas are a little more cramped than others.  Some helicopters that I rather liked were jammed together.  There is a shortage of space I guess, though, because lots of exhibits are outside and there are a few still scattered around the parking lot awaiting restoration.  That is not a criticism though.  The museum has plenty of great stuff to see (although the Beech Starship was in the parking lot last time I was there and still is, looking a little more forlorn now than it did then).

If I were to try and pick out highlights, it would be tricky.  The Spruce Goose is the main feature of the original building and it still dominates things there.  Indeed, it is so large that, at times, you actually forget it is there because it either is way above you or it fills the view becoming invisible in the process.  The SR-71 is a delight to see at any time and the way that one engine pod is opened up is a nice touch and gives a good idea of the installation for a unique engine.

The rockets and missiles are well displayed and I shall come back to them in another post.  Some of the aircraft are painted up in unusual schemes although these are not always original to the airframe on display.  Even so, they are a change from what you might normally see.  Having a 747-100 parked outside the front of the museum is a nice touch too – a reminder of Evergreen’s operations before the airline went bust.

I only had a couple of hours so I was in a bit of a hurry working my way around but this is definitely a place that you could spend a lot of time.  The journey there is long enough to make doing so something that you should really plan for.  I saw plenty that I had seen before but plenty that was either not there or was not displayed in the same way.  If you are in the vicinity, make a trip to McMinnville.

Easy to Guess Who You Work For

At was at BFI awaiting the arrival of something and I was checking FlightRadar24 to see what was coming in.  I saw a Learjet 60 on the screen south of SeaTac and tapped on it.  As soon as I saw the flight path, it was clear who the jet belonged to.  The shot below was what I saw and the repeated patterns around SeaTac suggested it was an FAA aircraft undertaking calibration flights for the airport instrumentation.

I stopped thinking about it for a while until I saw a jet appear on the approach to BFI that I hadn’t been aware of.  Sure enough, it was the FAA Lear 60.  They plonked it down right on the keys and quickly exited to the FBO.  I imagine that flying repeated sequences of approaches is not the most exciting way to spend the day so they were glad of the break.

Floatplane Fest

I was in Vancouver for a few days for work and I managed to catch up with my buddy Mark when I arrived.  He suggested to me a good opportunity for shooting the floatplanes is at the end of the day from Brockton Point in Stanley Park.  I had only shot them from the shore near the convention center (other than an opportunist shot or two while walking in the park and that doesn’t count) so I was interested to see how this location worked out.  I managed to get out of work at a good time one evening and the weather was looking very nice so it was off to the park for me.

This location is a lot of fun.  In the evening, the light is well positioned and, at this time of year, the sun is lower and the light is nice and just gets better and better as the evening sets in.  The aircraft were arriving from the east so they were very distant but it is the departures that we were after.  The planes head along the shore from the base and then turn towards you and start their run.  Often, they are pointing straight at you for a while.

Depending on the type and the pilot, they can climb steeply or can keep it nice and low as they come by.  Sometimes, there might be a boat on their preferred take off run and, since they have to divert to one side which can result in a nice turn back towards you as they round the point and head to Lion’s Gate.  The Otters are the most common type with the Beavers coming second.  There are still some Twin Otters but they are a lot less common than they used to be so they end up being more interesting when they show up.  How can it be that I get complacent about seeing Otters on floats?  (The fact we have them in Seattle too probably doesn’t help!)

Mark certainly called this one correctly.  Brockton Point is a nice place to hang out on a sunny fall evening in any circumstances but the addition of a steady stream of floatplanes to this makes for a wonderful combination is you are someone like me.  What’s more, it is a reliable option.  Until the winter light stops flying at the end of the afternoon, you have scheduled departures to rely on so this is not a case of turning up in the hope of seeing something.  You will definitely get plenty of planes.

787 Development Jets

Two versions of the Boeing 787 have been in service for a while.  However, development activities continue.  The 787-10 is still undergoing flight test but work also continues on the older jets.  Some of this is also related to the Dash 10.  I had a post on my first encounter with the 787-10 which I wrote about here.  I have since come across another of the test aircraft.  This one is plain white and doesn’t benefit from the nice house colors that Boeing has.

Meanwhile, one of the 787-8 test aircraft has recently been testing the newest version of the Rolls Royce Trent 1000.  I saw this engine when it was being tested on Rolls’ testbed in Tucson and that was in this post.  Now it has been fitted to its intended platform and is undergoing trials.  These have included lengthy flights around the US including one in which they traced out the planform of the aircraft across multiple states.  If you are going to go flying for 18 hours, you might as well find a way to have fun with it.  The aircraft is carrying the same logo on the engine nacelle that was on the testbed.  Hopefully, the delayed upgraded engine will soon be in service, not just on the Dash 10 but also on the other variants.

Does No-One Want This 747? Tell Me the Story…

This is a request for information from anyone who might know the story.  The 747-8I has not been a huge success for Boeing.  It has sold in limited number with the biggest customer being Lufthansa.  A long time 747 operator, they ordered 20 of the aircraft.  However, they only took delivery of 19 and cancelled the remaining aircraft.  Boeing had originally taken it back to use for trials work and they retained it afterwards.

For a long time, it was stored down in Arizona.  Recently, it was reactivated and I saw it was coming up to Everett again so managed to catch it arriving.  Since it arrived, I don’t know what it has been used for.  I also don’t know why Boeing decided it should return.  Perhaps there is something more to happen with it.  I understand that the two jets that were originally destined for a Russian airline but were never delivered are going to go into the Presidential transport program but I don’t think this jet is part of that.  Does anyone know why it is back?

Floatplanes Coming at You

Standing in Gas Works Park, you have a view straight down Lake Union.  At the other end of Lake Union is one of the bases for Kenmore Air.  They operate floatplanes from there on a regular series of services as well as some sightseeing trips.  We got there just as a bunch of planes took off in close succession and I was a bit annoyed to miss out the chance to get some shots of them.  However, they are a busy company so we knew we would get some more flight before too long.

They start their takeoff run at the other end of the lake so they get airborne long before they reached us.  With so much clutter in the background and a lot of ambient noise, you didn’t always immediately pick out that a departure was coming your way.  Once they got airborne and a lot closer, they were easier to identify.  They would turn before they reached us and head off en route.  I could probably have spent a lot of time there watching the flights but Nancy is not quite so keen so we lingered a short while and then moved on.

Emirates’ Latest on Test

An Emirates 777-300ER is hardly a rarity.  They have a huge fleet of them and, since this one is a new build aircraft on test at Boeing, the fleet is going to grow.  What made this one fun was the light.  Some stormy weather had been in the area and the sun was out on the white fuselage while the background was still looking rather mean.  Both on the runway and on the approach, it shone brightly against the background and that is why I am sharing it today.

They Both Float, But…

This is the cruise ship that our family had been traveling on when they arrived in Vancouver.  It was heading back out the same day and we watched it leave port and head out.  As it was turning to head back to the open sea, one of the local Otter floatplanes was making its approach to land (or whatever the correct word is when it is water rather than land).  It passed in front of the ship.  Both vessels are comfortable in the water but one is on a rather different scale than the other.
