Unidentified flying object (UFO) and lights in a cloudy sky,computer artwork. This UFO is known as a 'Black Triangle',and theories explaining what it is range from an alien spacecraft to top secret military aircraft. There are several aircraft that use triangular delta-wing designs (such as the US B-2 Spirit stealth bomber),and these lights look like aircraft landing lights. There is no evidence that conclusively shows that alien spacecraft have ever visited Earth | |
