Pair of Pumas
A friend has mentioned to me that over the last days he's seen a 'pair of black large helicopters that you can see through' several times in different places around London and twice where one has done and infil/exfil whilst the other does a few circles to then head off again as a pair. I've narrowed it down to a Puma(s) as they have a single set of main blades with sliding doors on both sides that would allow them to be 'looked through' as it were. Assuming that they're not French or whomever, they must be RAF variants, but I don't recall them being black/very dark grey whenever I've seen any. Anyone know what they are/ were up to ?
