One of my sales outlets is through Alamy and I make a little money each year through them. A recent and decent sale was for this image at just under $200. I think David Bennett commented on a close-up version of this very same jet turbine. The shot was taken at the Farnborough airshow back in the summer and is a total profit for me, as a friend of ours very kindly got us VIP tickets to enter the show.
Alamy launched their “News service” this year and this was one of my first uploads via that channel. So very encouraging
