A little switch from flowers

I was out by the airport again on Saturday.
I heard it first, an entirely different sound from the usual aircraft. I mean normally there's a higher pitch, almost a whine. This one was more like a rumble. Then, looking at it, one could see it was different. The fuselage in unpainted. It just shines.

Unfortunately, by the time I grabbed the camera, there wasn't time to set it to shoot video and I could see the LED screen well enough to use the telephoto. So we'll have to settle for this image until such time as I spot it again.

It may be a Beech Model 18
