Grid and Grid
I went out blip-hunting this afternoon. The weather was overcast, the lighting dull and no aircraft were out at Old Warden (all the excuses . . .). But on my way home I crossed the level crossing at Tempsford and stopped below the high tension wires.
I've snapped a standard pylon from below, at the RSPB reserve near Sandy, but this is from above next to a solar panel farm. I was really careful to ensure that I had a proper signal, that the GPS was functional and that I had calibrated my drone's compass, all to ensure that any radiation from the wires would be less likely to interfere with my control of the drone (a Mavic Air).
Then I climbed well above the pylon lines so as to avoid any problems with parallax fooling me into getting close to the wires or the pylon and I really liked the view of the pylon from above.
Then on the descent I got complacent, or lost attention for a moment and I nearly crashed the Mavic into a thorn bush near the road! Quel idiot! A moment's inattention . . .
