Perhaps these tutorial videos of Tom Blands, can be helpful to you.

That looks good, Akros. :2thup

Just a couple of small artifacts left behind that can be fixed manually.

Very typical case of drawing a path that follows the plane outline and then using it as a selection.

Done in 5 minutes (you can improve on it, by including a few protruding things that I left out)

PM me a mail address if you want the XCF with the path (5MB)

I think ofnuts's approach would be the best way to remove the background, given the overall colors within the image.
I usually employ this technique to remove the background from an image, but there needs to be some good contrast of colors in order to use this method... https://www.youtube.com/watch?v=AnbxtMCHKV0

IMHO it is the only valid method on most man-made objects, because it is the only one that preserves straight lines and smooth curves (it can even reconstruct them...). And once you have learned the moves with the path tool it is quite fast.

Thanks all of you.
I use Path tool and I think it work, but the first path and the last one don't connecting to each other?
I think I doing something wrong because everything turned white.

Thank you.

Use Ctrl+click to connect the start and the end anchor points. You'll also notice the change in the Path tool's tooltip.
P.S. Well, on Mac it is a Command key I think.

I happen to be working on a plane too... I spent a bit under two hours, for 290 points (actual image size is 3700x2100):

Excellent Ofnuts!
I looked for any failure, but the details were all preserved.

The fact that the cockpit is not transparent helped.
Technique and patience, commendable! :clap

Thanks all.

K1TesseraEna OK next time I try with CMD to connect the path.

Ofnuts. Perfect cut background from the airplane. Thanks for offering about XCF.

Having an accurate selection on the plane helped a lot.

Wery good ofnuts. Looks real. Do you know if there is a star engine on that machine. I made one few year ago for my Blender made Tiger Moth.
