Humid Air Show Days Mean Prop Vortices

We had some pretty mixed weather during the course of RIAT this year. There was plenty of sun but also some rain. Even when it was dry, the humidity levels were pretty high and this meant that anyone wanting to get some vapour shots was going to have plenty of options. For the turboprop powered aircraft, when they were putting on the power, it meant that their props were pulling tip vortices. Here is a selection of shots of different planes extracting water from the air during their take offs.

Darkstar (Not The Real One) and Blackbird (The Real One)

One of the bigger attractions at the Antelope Valley Air Show, held at Edwards AFB, was the appearance of the Darkstar plane from Top Gun Maverick.  Obviously not a real plane (and not even the real Darkstar which was a reconnaissance UAV that never progressed beyond testing), it was part of a hugely popular movie so garnered a ton of attention.  It was parked in the static display alongside a very real SR-71 Blackbird.  This was something I found far more interesting having seen them fly for real in my younger days.  The Darkstar was still fun to see. I am not that churlish.

Sentimental Journey In Damper Conditions

Glorious weather had greeted the B-17, Sentimental Journey, when it came to Seattle.  The following week, it moved up to Arlington but was not so lucky.  The skies were pretty overcast and the air was more humid.  It didn’t make for great conditions to shoot a bare metal aircraft.  However, many times before, I have written here about how poorer conditions can sometimes be worthwhile.  This was one of those times.

I started off shooting from further up the field and, as the B-17 started her takeoff roll, it was clear that the props were pulling a fair bit of vapor from the air.  Consequently, I headed further down the field for the next flight.  This also provided a close look at the plane as it taxied out.  The real benefit came when the power was applied.  Vortices were streaming from the tips of the props and swirling back across the wings.  It is always a tricky call when trying to shoot in these conditions.  A good bit of prop blur is good as is a blurry background to emphasize speed but, this will result in the vortices being less defined.  A faster shutter speed helps make them stand out.  I tried to get a good balance with the speed I chose.

Life Flight PC-12

PC-12s are a common aircraft in the North American aviation scene so this one is nothing special.  Seeing one on approach, albeit in nice light, is not cause for much celebration.  However, it does mean that, with the light on the nose and a prop spinning up front, it is worth dropping the shutter speed and getting some prop blur.  If I try and fail, I haven’t lost a shot of something that I wanted desperately to get and, if it works, it’s a bonus.
