a few days ago my following contrail picture was added to the database

I asked for a little help with the left aircraft type and got many many emails from a.net members/photographers. Thanks for all of them.
But, there were three different answers in the following order A330, B777 and B767... No one was quite sure, so I thought it might be a good idea to post a topic about this here. Maybe we can find the answer together... I'm really interested in it...
For myself, I would vote for the A330 after several emails from you.
Thanks for all your help in advance...
