That hangar does present you with a bit of a levelling nightmare.
One option to tackle this is to use the 'transform' function in PS, as I have tried to do in this edit below:
John's photo - corrected
Now I don't know if this would count as 'manipulation' (what does anyone else think on this?), but the plan here was to correct the distortion created at either side by your lens. You would need to do this with the original to ensure it looked better, as the process has cropped the nose off here. But now all the verticals appear as vertical. You may then need to tweak other aspects of the image, so the plane looks okay, but this is just to give an idea.
If you need any further help with this let me know.
