This photograph was taken in the skies over Upton Park just after 3 on Saturday afternoon.
It shows a DHL plane seemingly about to mount the back of a Japan Airlines jet, but the Civil Aviation Authority are having none of it, saying that no near miss has been reported and the photograph could be very misleading. Indeed, if the planes had stuck to their proper flightpaths (which the CAA says they did) then there would be more than two miles of sky between them in this photo.
A spokesman for DHL is quoted as saying:
In the picture, they look like they are close together but it doesn't mean they are. And in fact they were not.
If there had been any incident of them being close together, there are all sorts of systems which would have gone off, both in the plane itself and at air traffic control - but there wasn't any report of an incident.
Both planes later landed at Heathrow with no problem.
