Regarding the fuel truck - I believe the company obtained a new fuel truck about 2 years ago, following a collision between the old one and an aircraft taking off on a taxiway (by mistake). The new truck was slightly longer but otherwise looked identical to the old one. I guess thats the new truck in the c209 photo
Funnily enough, I actually knew the bloke who drove the truck. His name was Dwayne, and he was telling me the accident occured one day while he was driving along the tarmac. Another 207-900 was attempting to take-off on RWY 16, but mistook the RWY for a parallel taxiway - and due to the pilot's excessive aft CoG, visability was reduced over the nose, and a colision resulted. Dwayne was immediately sent to counciling, and still today, is deeply affected by those events that unfolded on that faithful day 2 years ago.
Also, i think you'll find Gunnadothat that those ripples were caused by yet another collision related to reduced foward visability.
