Who cares...who can say they havnt done something stupid or a little dangerous...and as for standing on roof of van thats pretty low danger in my opinion.
If he was using a for example a 24ft pole and the window was just out of reach for one job, sod spending £200 on a 30ft pole or more, ill stand on my van thanks for free.
If he was needing to get that high all the time then go get a new pole, but if its for one job like i say WHO CARES...you lot need to get a life sometimes, he didnt kill anyone, give the guy a break.
