I seem to remember that materials with high temperature super conduction started to become available in the 90's, just about the time that the triangles appeared. This might make practical the generation of magnetic fields sufficiently powerful to divert a gravitational field.
It was possibly an offshoot of Tokamak fusion containment research. I'm pretty sure there are plenty of people out there that are convinced that they are aliens, but I think it is much more likely that they are experimental US aircraft. I don't think that they are seen anywhere else than the US, UK and Europe, which tells me that the possibility of a malfunction and the technology falling into hostile hands is too risky at the moment. I wonder if this is part of Operation Paperclip finally made a practicality.
The CIA generated a lot of misinformation to disguise the development of the stealth fighter and I would guess this is just a continuation of the same.
