LightRoom v4x - best settings to process these photos

[astroNikon]

Tonight, while a storm was approaching and the sky was gray, our Local B17 returned from Washington DC and did a flyby of a local Memorial Park and a memorial that was going on there.
I certainly wasn't expecting it while mowing my lawn. I noticed this gigantic thing doing circles, ran inside, grabbed my camera and took a shots. But the lighting wasn't so hot with the sky.

So I'm wondering what are the best setting to process these to get the best image.
I put a few of the RAW images in a DropBox from my d600. I have lightroom v4.x
I'm good at a few things in Lightroom but these are a bit past my knowledge of using the curves or what ever.

Any help and instruction on what settings to use to get the best from the images would be greatly appreciated.

I DLed the first two and saw a smallish plane in a featureless sky.
Not much to work with.

Sorry, on my internet connection was taking way too long to even look at them.

Maybe add a sample jpg here so others can see if they are up to the challenge ?
