Possible cloaked aircraft?

[Skoshi Tiger]

Hi, I wonder if anyones come accross this one before

I was flying on the Syndicate server today and noticed what looked to be sunlight glinting off and aircraft. I hadn't seen that before so I vectored over.

As I got closer the aircraft apeared to be a puff of smoke that had a roughly aircraft shape as it passed over me. At about that time I started recording a track and did another flypast roughly level with the aircraft and this is what was shown




My game is the standard upto date steam install that has recently passed an cache integrity check. Could it be that someone has modded some sort of cloaking device?

Bit fishy if you ask me.
