Yes, on a mostly sunny day in May 2015, to add to an earlier one:
And actually, although rather fainter, there’s another one behind the big and obvious one.
What this photo also shows is how this phenomenon happens. Basically, there’s a big band of cloud that stops the horizontal evening sun lighting up the vapour trail, but the cloud leaves the sky behind the vapour trail still lit up. So, the vapour trail is turned into a silhouette. These circumstances are not common, which is why dirty vapour trails aren’t either.
If vapour trails always looked this this, air travel would have been a lot more unpopular and a lot more expensive.
Also, mmmm, cranes.
