Anomaly hunters turning their gaze towards the Earth rather than the cosmos suspect that they may have spotted a secret American aircraft via Google Earth.

The futuristic-looking anomaly was discovered sitting outside of a Florida building said to belong to aerospace company Pratt & Whitney.

Given the exotic appearance of the oddity combined with its location, conspiracy theorists were quick to suggest that the find could be some kind of test craft yet-to-be-revealed to the public.

Similarities to an unmanned combat air vehicle known as the X-47B have led some to speculate that it could be the next generation of that craft.

But not everyone is convinced that the discovery is a clandestine aircraft, with skeptical observers proposing that it may just be a model used for radar testing or, even more prosaically, a speedboat.

Considering the government's propensity for wanting to keep a lid of the development of secret aircraft, these possibilities seem to be more realistic options.

Otherwise, one would have to assume that someone from the aerospace company made a huge mistake by leaving their secret aircraft outside for all the world to see.

Should the view of the facility suddenly be replaced by a giant block of opaque pixels on the next Google flyby, the conspiratorial conclusion of anomaly hunters may need to be revisited.
