Alternative flight

Since the club plane we booked for a week had only had only a couple of engine hours left prior to go for revision, I have to develop an alternative for the planned flight to Southern France. So, we decide to go for the day to Koblenz. I plotted a route flying over all the Moselle castles and the dormant Volcano of the Eifel Region. The weather is nice and so we head for Koblenz
