Coming back from Sunny warm Italy, Germany naturally had to welcome us with cold, rainy weather. We arrived in the airport airspace and the captain anounced we would be circling up to an hour before heading to Cologne because the fog made landing too dificult. Luckely it lasted 20 minutes and we landed though the fog was only about 2 feet of the ground and visibility was next to nothing. Made it home safely and immediately went around orgainizing a party for later in the evening. Needed to catch up with everyone's break.
