My brother in law has been shot down by an Hitachi DH40 (big hex rotary hammer similar to a SDS max ,in fact nowdays still in production with the SDS max system) while was drilling from up a ladder .The ladder failed the bit jammed in the wall ,he made a complete turn in the air prior loose the grip fall to the ground .
Now, if you had got that on camera
I hope he wasn't hurt tho...
