90% of malfunctions are caused by bad body position or bad drills, or a combo of the two, so I'd vote for incompetent in the first instance, and thereafter lucky as fvck.
The 'lucky' bit being tempered somewhat by the fact that when the earth did rise up to smite him, he encountered roof tiles instead of a nice yielding fresh-ploughed field.
In the old days in Westonaria, there was an Italian bloke who who was into style and accuracy and didn't spikka da Eengleesh very beeg. Anyhow, there was an old truck used as a recovery vehicle if the spot was dodgy and anyone ended up in a neighbouring township. They'd sometimes go in mob handed to avoid lynchings.
One weekend Signore Tight Tuck was lobbed out of the Dak early on a bit of a shitty run in so as to allow the RW skygods to scrape their shit into one sock and get out the door by the time they were over the DZ. As a result thereof, he found himself over the township on a gusty day with nowhere to go on a PC. Ended up going through the roof of a house and interrupting a family at their lunch in a noisy manner. He looked around at the astonished faces and just as suddenly exited the building vertically through the roof as his canopy caught a gust and plucked him out.
Around that time the recovery pickup rolled up and he was dragged aboard before disappearing in a cloud of dust. A bit later someone arrived at the DZ to claim compensation which was paid out and off he went.
Shortly after someone else arrived and claimed compensation for the new roof. He was informed it had already been paid and went off in a sulk after a bit of shouting at the guys on the DZ. A few more rolled up over the course of the afternoon, all wanting to be paid out for their damaged roof and were told someone had already been there and had the money given to them. Lots of shouting ensued. No idea if the original claimant was indeed the offended party or if he was one of the others and managed to find the bloke and get his money.
