Hi Neighbour,
Continued watching it cross my field of view and noticed that one of the trails evaporated within 5 to 10 seconds whilst the other remained and expanded. This was slowly blown southwards but at 14:50 the remaining trail was still visible.
During my period of observastion c. 25 minutes - two other planes crossed in the North East to South West corridor at a far higher altitude - first was a twin and the second four engined. Both lost their contrails within 10 seconds.
As I said, I'm not really into this but thought you may be interested. Incidently, were your photos taken in Postamer Platz?
Peace!

Regarding follwoing post - the odd thing here is why trail from one engine should remain for 25 mins but the other last no more than 10 secs.
