Las Vegas airplane spotting

At the last day of CES this year I had few hours to do airplane spotting. In Las Vegas airport is basically in the city, so I only had to climb to the 8th floor of nearby parking lot to see the airfield ~2.5km from me. I was using Sigma 135mm F1.8@F2.8 with 24mp APS-C camera. Most of the shots were cropped to 100%, 135mm was barely enough even with 3.9µm pixel.

On the photos with visible engine exhaust you can see how modern high-bypass turbofan engines operate - "dense" trail is coming only from the core part of the engine.
