Do you believe the truth is out there? Or, like Scully, do you need a little bit more evidence before you're completely convinced aliens exist?
Well, maybe this new 'UFO' video will go someway towards helping you make up your mind!
The two-minute five second clip, uploaded to YouTube, shows a dark-coloured disc with lights on either side.
The craft appears to be flying above the cloudline.
According to the video, the incredible scenes played out above the capital on the morning of May 25th, being filmed from an airplane window by a keen-eyed passenger.
It has been viewed more than 92,000 times since it was first uploaded.
YouTube user Wayne McCabe was impressed with the footage, remarking:
"Cool intro and good video [sic]."
Another added: "Great capture ! Looks amazing! [sic]"
Someone else drew attention to another mystery, asking fellow users: "Interesting....anyone notice the light/shadow on the right casts an image of a face (more obvious near the end)?"
However one YouTube user was less bedazzled by the footage, writing: "That is obviously swamp gas or a weather balloon...
"And if it is indeed an unidentified flying object - then, it would be an experimental aircraft or some sort or another. Nothing to see here... move along [sic]."
