ITV4 (IIRC) last night.
Very good factual programme where the Police reconstructed the events leading up to two RTA's on the A38, one fatality involving a ped, and one near fatality involving a cyclist hit by a 32 tonne truck. Amazingly he survived.

Anyone watch it ?

No but thank goodness that the British Police are willing to go into forensic detail to investigate road accidents and establish the cause. In many countries a road accident is just dismissed as "unfortunate" or an act of God.

Not a road accident but I remember reading an account in the South African papers of a house burglary. The alarm sounded and the local security force came and saw off the burglars. Police came and left a young black constable to guard the house. Owner returned drunk from the pub, saw the black constable, mistook him for a burglar and shot him dead. The Police comment? "An unfortunate accident."

Plus a pretty strong stomach I'd guess.

The detail they went into was extremely involved.
Basically he'd been hit from behind by an articulated lorry. He suffered head, kidney and leg injuries. The rear wheel was folded right in on itself.
They scoured the verges for any trace of cycle light parts to prove, or disprove he was visible.
They re-assembled the shattered parts of his lights to try to see if they were indeed capable of working.
They couldnt find one of the batteries, so scoured the verges again looking for it..working on the principle they may have been dead at the time of the accident , rendering his rear light useless.
They scoured the road, looking for debris that may have proved he wandered into the path of the lorry.
They recovered his jacket and photographed it in the dark to assess if it had good visibility to others (the photos showed it had reflective strips)
They analysed CCTV footage if the roads before the incident to see if he was visible, were his lights working ?...they were indeed.
Even assessing his bald(ish) rear tyre and debating id that could have caused any loss of control (on the day it was dry, so they dismissed that theory)
A complete check of his cycle to assess for any defects that may have contributed.
Of course they checked the damage to the lorry, deciding what part he's impacted.

There was no mention of the speed of the lorry, but the deep scuff marks his helmet made on the bodywork left me in little doubt that it could well have saved his life. Surprisingly to me, the programme or police didnt make a deal about the fact he was wearing a helmet...the authorities dont usually miss a chance to tell you the virtues of wearing.

Thankfully the guy is recovering, his kidneys are shot but otherwise he seemed ok. He didnt even bear a grudge against the driver...'he's just a guy doing his job who made a mistake'.

Ultimately, they think the driver was maybe falling asleep and charged him with dangerous driving. He packed up driving immediately after the accident.

They took nothing for granted, nice to see the thoroughness of the investigation, good to see a happyish outcome.

I'm an accident investigator. I do have a mechanical engineering degree, but don't work for the police. Mainly because I don't work with cars (trains instead), and am an Incident rather than Accident investigator, and don't do it full time - its one of my skills/training. Don't need a strong stomach as I have only been involved with one fatal, and that was some time afterwards.

Is it interesting though? I always find this kind of stuff really fascinating. Nearest I got to mech eng was an msc (eng) in ergonomics. Didn't really give me the right skills though.

Back in the late sixties my dad killed an old boy who came out of a side road on his bike, over the limit on alcohol, half blind, half deaf, no lights, dodgy brakes and his family had warned him repeatedly about riding home from the pub in the dark. He came through the windscreen and died in my parents' laps. They were both medical so they weren't as traumatised as their passenger. The Police came and examined my dad's car in minute detail. filling in a thick questionnaire about the condition of the car, tyre treads, brakes, were the windows clean, wipers, lights, was the heater on - could have made him drowsy, did the floor mats impede the brake pedal and so on. Luckily the car was in perfect condition, otherwise he'd have been prosecuted for manslaughter. When they measured the skid marks they put it to him that he must have been exceeding the limit; he admitted that he had been. However the case was for them so cut and dry that the copper just said "Let's say thirty then, shall we?" and that was the end of it. Maybe the fact that my Dad was the village doctor helped, I wonder if he would get away with it nowadays?

For the rest of his life my Dad used to flinch whenever a car or bike came up towards a side junction. What I learned was always to keep the car in perfect order and clean and well maintained - even my rusty old Land Rover always had perfect brakes, tyres etc and never failed an MOT in the 10 years I had it.

Depends on the incident. Bigger ones are more interesting. Some are just frustrating, where either the evidence that you want is not available, or where the failure seemed to have no possible cause. Working on one at the moment - bits were sent for investigation, and the report concludes "due to post-incident damage we cannot determine the cause of the failure". Can be quite scary when you see what damage a train can do to itself - big bits of steel twisted like plasticine, proper engineering steel bearing rollers smeared out along the running surfaces like butter.

But you always need to keep an eye on the fact that it is always a sequence of failures that led to the incident - an investigator who blames it on one person can't do their job properly.

Favourite one was many years ago - attended the scene and picked up the evidence. I saw a small piece of metal that looked unassuming, but in my eyes was out of place. Put it in my pocket, forgot about it, had to drive to my manager over the weekend for him to take to the meeting on Monday, and it was eventually decided that this bit of metal was part of a failed spring that had been the cause of the incident. Feels good, that does.
