KC-135 Stratotanker Mid Air Refueling of F-16’s

I had the opportunity to fly in a KC-135 out of Homestead Air Reserve Base this past week on a training mission to refuel F-16’s over the Gulf of Mexico. The F-16 MAKOS from 482nd Fighter Wing out of HARB were participating in simulated dog fights and training exercises as well as mid air refueling.

The KC-135 only has 4 small windows in the side of the plane. Two on the front doors on either side of the wing and two toward the tail of the plane. This made it difficult to frame my shots as there were not many viewing options in addition to not much room to work with without getting the edge of the window in the viewing frame. Also, like most airplanes the windows are made from a thick acrylic that has various scratches across its surface. I was afraid this would have an effect on the image quality but except for a few images, the final product was not really affected.

In the belly at the back of the plane is a space for the Boom Operator. The Boom Operator is responsible for lining up the approaching aircraft and successfully mating the boom (fuel hose) with the fuel receptacle on the airplane. To accomplish this their is a medium sized window at the rear of the plane just below the boom for the operator to look out of and gauge the distance to the plane to be refueled. Their is space on either side of the operator for other workers, or in this case observers, to watch the refueling process. This is also the only space available to try and capture a photo of the approaching F-16’s. Once the F-16’s are connected to the boom they are so close that their nose cone is located below the window and therefore out of sight of the camera’s lens. During the fueling process the plane was less than 30 feet from the back of the KC-135.

Each F-16 only took 2-3 minutes to fill up their tanks before disengaging and moving out of the way for the next F-16 to arrive. Prior to refueling, the F-16’s would stack up on the left side of the plane and then one by one drop down to refuel. After refueling, the pilot would then move to the right wing and stack up waiting for the other planes. All of this was taking place at around 34,000 feet and nearly 500 knots.

One thing I noticed was that each time a plane successfully attached to the boom the entire plane would sink and lose altitude for a few seconds before leveling back off.

For the refueling, I chose to use my Canon 16-35 f/2.8 II lens to ensure that I could capture the entire plane and some of the surrounding landscape. This required me to reach all the way up to the window to ensure that I did not get any glare from the window and also did not capture the inside of the airplane. For the side window shots over the wing I used my Canon 70-200 f/2.8 II to allow me to get tighter crops on the planes than I could capture with my wide angle lens. I shot in aperture priority to ensure my depth of field was sufficient to capture the entire plane and boom in focus. It was a very sunny day, especially at 34,000 feet so I had plenty of light to work with.

On the way back from the training exercise I was able to sit in the cockpit on approach and while landing. It was a very unique experience both educationally and photographically.

Keeping Lens Filter From Binding Onto Camera Lenses

I frequently use lens filters with my lenses for my landscape photography such as circular polarizers, neutral density filters and step up rings. Inevitably they always seem to get stuck on my lenses at the most inopportune time. I then spend the rest of my photo shoot trying to get the lens off or, if I just leave it on and try to work around it, frustrated that the lens filter is stuck.

Luckily, I have always eventually been able to remove the stuck filter. The same cannot be said for some other photographers I have spoken to. Some of them have had filters on their lenses that have been stuck for years. After the most recent occurrence I started thinking there had to be some way to keep this from continuing to happen. After spending some time researching I finally found a solution that works and thought I would pass it on to my fellow photographers.

From my research there were two (2) primary approaches to keeping lens filters from remaining stuck in perpetuity. The first was using tools to remove filters after they were stuck, the second was taking preemptive action to keep them from getting stuck in the first place.

For removing already stuck lens filters it seems the best tool for the job is a lens filter wrench. These cheap accessories apply equal pressure to the filter and from all accounts easily remove the filter from the lens. The lens wrenches usually come in packs of two (2) and can be had for less than $10.00 at your local photo supply store. Even if you take preemptive actions it is not a bad idea to own and carry this item with you on your photo excursions.

To keep lens filters from becoming stuck in the first place, the best solution is to use good old pencil lead. Turns out pencil lead is primarily made from graphite. Graphite is a great dry lubricant and does not cause a mess, smear on the lens or attract additional dirt and grim that is likely to cause the lens to get stuck even more frequently. Without getting into to much detail, pencils are labeled based upon the level of graphite they contain. The softer the lead the more graphite it contains. The softest pencil available is a 9B the hardest is a 9H. These pencils are typically only found at your local hobby store. However, many people use the standard No. 2 pencil as well. Here is a link to a more detailed explanation of pencil hardness http://www.cultpens.com/pencyclopedia/lead-hardness.

For me I went to my local hobby store and picked up a 6B which happened to be the softest they had in stock at the time. When I got home I proceeded to rub the lead on the threads of my lenses and my filters. I then blew off any excess powder than did not stick to the threads. I am happy to say that I have not had any stuck filters since taking this preemptive action. I also now carry a lead pencil in my photo bag with me and occasionally add a new layer of lubrication to the filters.
