Geometry in Housing or is it Monopoly

A quick trip to Dallas for work was necessary and I took the little camera along for the trip. As we came in towards Love Field, we flew over ares that are in the process of being built up or have recently been so. Seeing plots of land with the street layout showing but the plots not yet built up showed what had been there before in the areas that were now populated. A closer look showed that the houses did have a variety of styles but, from above, the roofs all seemed to be very similar and they were close together. It was almost like someone had grabbed a bunch of houses from a Monopoly set and lined them up next to each other. On the ground it probably looks nice but from above it was very uniform.

El Al 777 Overwing Vortex on Takeoff

Leave a reply

Engine nacelles are optimized for cruise performance. At high angles of attack, their shape results in some rather awkward flow properties which can influence the wing performance above and behind them. In order to control things, you will see small vanes attached to one or both sides of the nacelle that generate a vortex that stabilizes the flow somewhat. As an aircraft rotates at takeoff, the strength of this vortex increases and it will often become visible as moisture in the air condenses within in. This vortex will stream back up and over the leading edge of the wing.

When you are inside the aircraft, this is pretty easy to see provided the conditions are right. From head on or aft they are also quite conspicuous. It isn’t often that you get a good view from above. When I was flying over LAX in the helicopter, the aircraft departing from the north complex had better light on them. However, the runways are offset so the rotation point is further west and beyond the area in which we are allowed to fly. However, you can get a view from above and behind as the jets get airborne. An El Al 777 took off while I was up and I managed to get some shots of it as it rotated and climbed away and the vortices were clear to see as the angle of attack increased.

Manhattan Sunset

Leave a reply

My departure from New York was out of Newark Airport. The day was coming to a close as we taxied out for departure and the turn after take off gave me a view back across towards Manhattan. The sun was getting low in the sky so, while the sky behind the city wasn’t glowing, the light on the city was really nice. Not a bad view as you start the long trip home. Fortunately the winds were favorable and the trip back took an hour less than expected!

Gulfstream from Above

Leave a reply

Getting the airliners coming in to LAX was what I was aiming for but I was pleased to get a bizjet bonus. A Gulfstream made an approach to the northerly runway complex. This was a surprise to me as the facilities for corporate aviation are on the south side of the airport so an approach over there would seem to have made more sense. As with some other arrivals, I wasn’t complaining. An aerial shot of a Gulfstream was very welcome.

BB-8 to Add to the ANA Star Wars Collection

Leave a reply

Back when we lived in California, I saw the Star Wars 787 from All Nippon come in to San Jose. That is the topic of this blog post. There are a couple of other Star Wars planes that ANA painted up. One is a 767 and it tends to fly around Asia so I doubt I will get a chance to see it any time soon. The other was a 777-330ER painted up like BB-8. I few of my friends have seen it come in to Chicago but I had not seen it up close. They didn’t operate in to where I was. (I had shot it overflying me at high altitude once though.)

Then I caught a break. I didn’t realize this at the time but it was operating to Los Angeles the day I was shooting over the airport. I knew an ANA 777 was on its way in but I had not paid too much attention to which aircraft it was. As I was hanging over the airport, I picked the jet out of the murky skies as it came down the approach and, as it got closer, I realized which jet it was. I have to admit, I was rather surprised and a bit excited when I saw it.

Boomer Position in a 747

Leave a reply

If you think of aerial refueling tankers, the Boeing 747 is not going to be the first plane that jumps to mind. However, a tanker version of the 747 was developed and is in service to this day in Iran. I haven’t seen one of those planes but, before they were built, Boeing undertook testing of the configuration on their testbed, the original 747 prototype. This is on display at the Museum of Flight in Seattle. When we were walking through the fuselage, we got to the read and found the boomer station. Apparently, it was not removed after installation. It looks remarkably similar to that from a KC-135 so I guess they ported the design across rather than come up with something significantly different.

Aerial Views of Seattle

Leave a reply

My brief trip to the UK was concluded by a flight back to Seattle from London. I ended up in a seat on the right side of the plane and, as we came across the city, I had a good view of the downtown. The seat was rather low compared to the window but LiveView came into its own and I could hold them camera above me pointing down and frame the shot using the rear screen. Technology is a wonderful thing. The Space Needle and the football and baseball stadiums both stand out from above.

Departing the Bay at Sundown

Leave a reply

This post may seem a bit symbolic but it is a bit of a cheat. I flew out of SFO heading up to Seattle to go to my new place. The flight left around sunset and, as we climbed out above the bay, I got some lovely views of the water, the city and the cloudscapes with the last light of the day. As the sunset on my time there, it was rather appropriate. (The reason it is a cheat is that I came back a few days later and left again by car. That wasn’t so dramatic so I shall stick with this version instead.)

Looking Down on DC

Leave a reply

I had to make a quick trip across the country to D.C. recently. It was only a brief visit so I didn’t travel with any camera other than my phone. I originally thought the flight back was very early in the morning but it turned out I was mistaken and we took off once the sun had come up. We departed to the north from National which takes you towards all of the most famous views of the National Mall.

The flight path involves a turn away from the good view so you are fighting the appearance of the engine and the wing when trying to get a shot (and that doesn’t take account of the battle you have with the high quality windows of your average airliner. It is the best view you get of the area though so well worth a go. Shooting in RAW also helps to fix some of the issues you can get with a phone when the shooting opportunity is fleeting.

Evening Over the North of the Bay

Leave a reply

These shots come from a little while back. When you are doing an air to air session, there is a fair bit of spare time. Unless you head out and back in formation, you have the transit time to yourself sitting in e back of the camera ship. You can stare out of the open door and see what is drifting by. We were heading back to Sonoma and so I got a great view towards the north end of the bay. The light was dropping down as evening came in so the hills and the marshes looked really pretty.
