not Jet ranger---Squirrel just flown back

[helirobin]

very dark colour, sun all wrong before, heading back ESE same sort of height, same odd "old fashioned" TV aerial/crop spray boom underneath. What is it?

It'll be a LIDAR survey... (http://www.pprune.org/rotorheads/222376-blue-silver-squirrel-strange-appendages.html)

Having viewed the pic of G-TOPS with its aerial, that was exactly what it was but not TOPS unless its had a colour change, definitely a squirrel

A dark red/burgundy Squirrel doing utility work probably belongs to PDG:

Definately PDG. Will probably be about all week...
