Inlet Vapor for the Heavies

More shots from a fun shoot a while back.  If the wind is coming from the west, evening departures from O’Hare provide plenty of opportunity to get some shots.  The heavy departures to Europe leave later in the afternoon and in to the early evening and, as the sun drops down things are getting better and better.  The nice thing about this day was that we got a combination of good conditions.  Earlier in the afternoon, while the light wasn’t as good, a storm had not long passed through and there was plenty of moisture in the air.

The result was a lot of vapor in the inlets of the jets as they climbed out at high thrust settings.  Some of them had clouds sitting in the inlets for long periods of time.  Others would just pulse with the vapor as they climbed away.  They would also puff up little clouds over the upper surfaces of the wing as they fought to gain height.  As the afternoon wore on, the air dried out a bit and the vapor went away.  However, the light was then getting better so no reason to go just yet!
