Help with contrast

[AdLob]

I would like some advise regarding the following picture rejected for too much, too little contrast.

What must I do to correct the contrast issue in this picture. I always get a bit confused by this rejection reason, but now I really don't know what to do, is my computer screen so uncalibrated at this moment or is it a editing problem
Thanks in advance to everybody who wants to help

A picture like this lends itself to a perfect black silhouette image on top of the sky. At the moment it's washed out where you've tried to include some detail in the aircraft.
Move the midtone (centre) slider arrow on the baseline to the right to get a value of about 0.3 and you suddenly get quite a stunning image, especially if you can reprocess and remove the sharpening jaggies.....
