Gulf Air 787-9

I caught this Gulf Air 787-9 as it returned from a test flight to Paine Field.  It was at the end of the SkyFair event so the crew will have noticed that there were a lot of people on hand to witness their landing.  Not a particular problem of course but probably one of the few landings of the Boeing production tests to get a large crowd.

West Seattle Bonuses

We made a trip to West Seattle with our guests while they were here.  We were looking at the view of the city and also wondering what wildlife might show itself.  I got a benefit in that departures from SeaTac and Boeing Field were coming to the north.  I got a couple of nice airliner shots as they climbed out over us.  They weren’t the only ones though.  A KC-46 launched out of Boeing Field and climbed over us as it went off to its test area.  I wasn’t paying attention, but my guests spotted something rocketing up behind it.  An F/A-18C Hornet from the Strike Test unit was following it, presumably for some test work.  It climbed rapidly but then leveled out, I assume to stay below the departure routes from SeaTac.  Not a bad bonus for me while showing the sights to my guests.

A Further Trial in Focus Stacking

In a previous post I wrote about a focus stacking effort I made with images of a model aircraft at a show.  I had been meaning to have another go at this and do so in a more controlled environment.  I then ended up buying myself a macro lens for use in my negative scanning efforts and immediately started playing with it to shoot things close up – it’s a macro lens for goodness sake!

As an f/2.8 lens, when shooting macro shots, the depth of field is really shallow.  This got me thinking about trying another focus stack.  A small Leatherman seemed as good a target as anything.  I set up with manual focus, put the camera on a tripod, went to manual exposure and then shot a sequence with small changes to the position of focus for each shot.  Then it was off to Photoshop.

Photoshop did a pretty good job really.  The distortion of the areas out of focus means that the area that the subject covers can vary quite dramatically as the focus shifts backwards and forwards.  The algorithm did well getting things masked and blended.  The only bit it struggled with was at the very top where the knurled edge seemed to confuse it a bit.  The top shot is the finished effort while two others are included to show how much things are out of focus in the individual shots.

737 First Flight

I was walking along the trail that goes through the park next to the airport at Renton taking a look at the stored jets.  There is a bridge across the river that is used by Boeing to move jets from the production areas to the flightline and, as I got close to the bridge, I could see the tractor hooking up to a China Southern 737-800 that had yet to be painted.  They looked like they might bring it across the bridge.  I figured I might linger and see what was up.

Sure enough, they started to pull the jet out and towards the bridge.  I stayed out of the way but the wings of a 737 hang over the trail when they are moving it.  This was not a problem so they were happy for me to stand there as the jet was moved out.  I figured a little iPhone video was in order.

They pulled the jet onto a taxiway and left it there so I figured it might be heading out on a test flight.  With the light now slightly to the other side, I chose to go back to the car and move to the overlook on the west side of the field.  The jet was starting up but they clearly had a few things to run through so I had time.

They taxied to the south threshold which initially disappointed me.  The wind had flight operations in the other direction which would have meant a takeoff towards us and into the light.  Going the other way meant they would be airborne a long way away and heading over the lake.  What I hadn’t figured on was, just like at Everett, they would do a run with an abort first prior to flying.  They carried this out and were then at the north end of the field.

A turnaround at the far end of the field and they were soon lined up.  A floatplane was flying about in the background as they got ready to take off.  Then it was power on and rolling.  There was a lot of crap in the foreground and this was a bit of an obstruction at the point of rotation but I was able to get some good shots as they got airborne and climbed out past us.  The green primer/protective film was glinting in the sun.  The flight will have ended at Boeing Field where I hope everything was trouble free.

RAT Noise

UPS is buying a bunch of 747 freighters at the moment.  I have shot a few of them including examples here and here.  The route back to Paine Field takes them across our area when the pattern being flown is a northerly.  I grabbed the camera to see this primer example heading over.  As the plane flew by, there was a lot more noise than would be normal for a jet on the approach and it had a vibrational element which made me think the RAT might be deployed.  Sure enough, when I checked the shots, the RAT could be seen under the wing route.  This is a normal flight test requirement so nothing to be concerned about but this was the first time I had heard a jet at speed with the RAT out and I was surprised how loud it was.

One of the Early F-16s

The early versions of jets are often repurposed throughout their life.  They serve a role for testing but they are not configured like production jets and to make them so is too expensive to be worthwhile.  Besides, they are instrumented to some extent so they can be useful for carrying out alternate tests.  As a result, they often get used for trials, research tasks or development of alternate concepts.  The early F-16s did a lot of this sort of work and ended up in some odd programs like the AFTI effort.  Sitting outside at the Frontiers of Flight museum is one of these test aircraft.  It spent its life with General Dynamics (now Lockheed Martin) at Fort Worth and, once it was done with, it found a new home at the museum.  Compared to the average F-16, this jet will have had a lot of interesting experiences!

Max7 Test Aircraft

The 737 Max8 and Max9 Jets are both certificated and in service.  Next to come along is the Max7.  It is a lower priority as a result of a far lower level of orders combined with a redesign it underwent to make it larger than originally intended.  It is now flying though.  I saw one aircraft on the ramp at Renton when passing by and also saw the first test aircraft landing at Boeing Field.  I actually saw it take off as I drove in to the city heading to a meeting and it returned at the end of the day.  Neither the Max7 nor the A319neo has sold well so it will be interesting to see how many of these enter service.

Going Mirrorless

Being late to the party is something that I make a habit of.  You could also be more optimistic and say that I am not an early adopter.  A number of friends and colleagues have added a mirrorless body to their collection of gear and I have followed suit.  I am perfectly happy with the performance of my SLRs.  This was to add something rather than replace something.  The primary interest was in size and convenience.  There are times when lugging the heavy bodies around is just inconvenient.

I went with an EOS M6.  I did consider going with a different manufacturer but using other equipment I already have was one factor.  Another was that this camera gave me an option I was quite keen on.  It has a screen for use while shooting but it also has an optional viewfinder to slot into the hot shoe.  This was discounted to only $11 when I bought the camera.  I like a viewfinder hit am okay with a screen.  Nancy, on the other hand, does not like screens so the viewfinder can be brought along if required and will make her happier to use the camera.

So far my experience with it has been very good.  Image quality has been fine, the controls are good and let me make adjustments without needing to enter menus.  The flippy screen is really handy and the kit lens fits plenty of needs.  The app that works with it is also pretty handy which gives a few options I wish the SLR could match!  The time lapse functionality is good too.  I have not tested it fully with my range of lenses and will do so at some point.  However, for what I bought it for, it is doing the trick nicely.

Pegasus Testing with the Hornet (and it’s not raining)

My luck with KC-46s and bad weather broke recently with a Pegasus launching out of Boeing Field on a glorious day.  It was carrying out trials work with a US Navy Hornet.  This jet was the subject of its own post.  The KC-46 followed it down the runway.  It rotated in a good location and the light was so much nicer than I have had recently so I was very happy to get shots of it as it climbed out and headed off to the airspace set aside for testing.

Salty Dog Hornet Goes Tanking

The never-ending test program for the KC-46 Pegasus involves testing with a variety of receiver aircraft.  Recently, the Navy has deployed jets to Boeing Field to work with the tankers.  While I was there, it was a Boeing F/A-18D Hornet that was sent across.  Operating with the call-sign, Salty Dog, the Hornet blasted out of the field ahead of its tanker.  They were scheduled to be up until after dark so I didn’t hang around for their return.
