Long exposure photo question...

[Thebuzu]

When using long exposures while an aircraft is either landing or taking off, should you upload the info as:

Runway
Airport

or use the aircraft reg? (If the fuselage is not visible, but you can only see the lines of light from the wing section)

By the lines I mean like in this one:

IIRC you're supposed to try and figure out what airline it was and if not just use Runway/Airport. You shouldn't have to find the reg#.

I am happy for it to be uploaded under the 'runway' guidelines.
