I have come across some flying with Hughes 500s at Boeing Field when someone was using a strobe to track the rotors as part of the maintenance. I figured that would be a one off but another time I was there, the same thing happened – this time with a 369. I would have loved to have been onboard when this was being done to see how the tracing of the blades looks in flight when the strobe is flashing. I imagine it would be quite an interesting engineering thing to see.

Weird Prop Vortex Effects on the Background
The aerodynamicist in me gets a little happy when I see shots that have the visible effects of the flow fields around a plane. Shock waves will be the most obvious example, but a trailing vortex can also cause some interesting refraction. The propeller produces a strong vortex from each blade and every once in a while, you can get a shot where the background provides enough of a pattern to allow the prop vortices to show up. I was reviewing some shots from Boeing Field of a Malibu Mirage with the PropJet turboprop conversion when I saw exactly this. Head on it can show quite well but getting it from more of a side on position was a nice surprise. Thankfully, the hangar doors in the background have vertical corrugations and this allows the flow to be seen in both directions due to the upward and downward moving blades.
We Can See Where the Fuel Is
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.
A Pair of PC-24s Overhead
I was out of position one time when at Boeing Field. Being down near the museum, departing aircraft tended to be quite high by the time they got to me. This didn’t stop me trying some shots since it was something a bit different. I was pretty happy when I got a Pilatus PC-24. They are quite popular and not a rarity at BFI but still pleasing. Then I was rather surprised to get a second not too much later. The PC-24 has great short field capability and can land on grass strips too. From the underside, you get a good look at the wing planform that delivers this performance.
A Pair of MC-12s But Only One Moves
I don’t know why two MC-12s might be showing up in Seattle. Maybe they have training requirements that involve deploying to random places or maybe they were intently listening in to the people of Seattle. I suspect that might not have been super interesting but you never know. Whatever the reason, there were two of them parked on the Modern ramp at BFI a while back. Normally a King Air would not get me terribly excited but stick lots of lumps and bumps on it and now I will show some interest. I was hoping that they both might fly while I was there but only one was fired up. It as a warm day and heat haze was not on my side so the ramp shots were a bit ropey. At least the one that flew came closer when it headed to the runway so I could get a slightly less hazy shot!
Messing Up the F-35B Departure
Since I switched to my R3 bodies, I have been playing a lot more with low shutter speeds to emphasise speed in images. This has been a topic in multiple posts on the blog in recent years. However, it doesn’t always work out well. I know that the keeper rate will fall when shooting fast moving objects at low shutter speeds, but you hope/expect that you’ll get something worthwhile from the ones you take.
However, that doesn’t always happen. During Seafair last year, the US Marine Corps F-35B departed Boeing Field for its display. I decided to go low with the shutter speed from my location up on the tower with the aim of having the airfield background blurring out and leaving me with the plane as the dominant element in the shot with little distraction. However, when I came to go through the sequence of shots that I took, I had some sharp ones as it approached me and as it flew away but nothing that really pleased me as it was closest and alongside me.
Some of them weren’t terrible but it was a huge disappointment as I clicked through the images and came to the realisation that I had blown it. You can’t always get lucky, and I knew what I was doing so I can’t be totally surprised that it didn’t work out, but it was still a bit galling. Does this mean I won’t do it again? No. Getting the record shot is fine, but I am more bothered about having a shot I really like these days. Might as well give it a go!
Bill’s Grand Caravan Takes a Spin
Boeing Field is home to a selection of aircraft belonging to one of the planets more wealthy individuals. The founder of a large software company has his biz jets and helicopters, but he also has a Grand Caravan on floats. In common with his other planes, the registration ends with WM. I have no idea whether he was onboard for this flight or whether it was a currency trip for the crew. It is a nice-looking Caravan (they look so much better on floats) and I guess I won’t be getting a chance to photograph it again for the foreseeable.
The Blues on the Ground at BFI
Another run back to Seafair from 2024. While I did get some good opportunities to photograph the team in the air, I also got to get a close up look at them while they were taxiing around at Boeing Field. The formation taxiing of display teams might not get much attention, but it is requiring a fair bit of concentration from the crews. Here is a combination of shots from different times during the course of the show weekend.
Under Condor’s Sandy Jet
The shot I always think about wanting to get is looking straight down on a plane in flight. Long ago, I discussed doing this with the WHF team at Waukegan, but we never made it work out. The next best version is the shot from beneath straight up. This is not so good because the fuselage shape is disrupted by the wing and a blank sky is never as interesting as the ground beneath. However, I do still like to shoot this sometimes. In this case, it was a Condor A330neo coming into SEA. This one is in the sand colours that they have. Probably not the contrast I would have liked but so be it.
Looking Down on Boeing’s Flightline
The first flight a Boeing 737 makes will usually take it from Renton where it was assembled to Boeing Field – a short distance away – where the flight test facility is located. Here the jets will undergo production flight testing and acceptance testing before delivery to the customers. Given the rate of production, that means there will always be a lot of jets parked on Boeing’s ramp.
Last summer, when I was up the tower at Boeing Field, I had a good view straight along the flight line. Further up the ramp were the active jets while the spot closer to the tower (where there used to be a viewing area before Max problems meant Boeing needed to park jets wherever it could find space) tends to be used for jets that are likely to be stored for longer – planes that were going to a customer that went bust for example.
