Vixen, let me postulate a hypothetical to you.
Let's say we have an event in which people reported seeing a bright flash of light. No one doubts that there was a bright flash of light, and that the witnesses are recounting said flash as accurately as they are able to do so. What can we conclude? We can conclude that something happened and it caused a bright flash of light that witnesses saw.
I hope you're following me and agreeing so far.
Then let's say we have someone come to a discussion of the event and say "I've spoken to an expert in flash photography and he says that the descriptions of the flash of light is consistent with flash photography".
Do you think this is sufficient to conclude that it was a camera flash?
I was woken up at 5:00am with a flash of light across my eyes. I realised there was a storm going on so went back to sleep. Later I discovered the storm had created some rather nasty havoc with a barn near our summer cottage being burnt to a crisp (not ours). With the triple glazing I didn't hear the thunder. This is very different from the flash bulb of a camera. I used to be into amateur photography with all the gadgets including flash. Flashbulbs are nothing like lightning.
However, say a whole bunch of people are at an event and there is an incident, after which people are asked for an eye witness account. You are not asking them for their conclusion, you just want to know what they saw, which should be in their own words, not yours. If some people relate they saw lightning, it simply confirms there was a flash of light. Your aim isn't to berate them for mistaking a flashlight of a camera with a lightning strike. 'Wrong! It was a flashbulb, not lightning, you twit!'
What you will have are a whole load of witness statements from which you can glean the sequence of events (a time line) what time, what did they see, what direction did the flash of light appear from, where was it directed, what happened next, why did you think it was lightning,
etcetera, etcetera.
So, if a whole bunch of passenger survivors, a reasonably good cross section of the public, albeit, nobody under twelve or much older than 65, and few females, ranging from barmen, to policemen, to PhD students, to musicians, report a series of 'bangs' and feelings of collision, why should you object to it just because it doesn't fit the narrative of a bow visor falling off?
Incidentally, several of the crew also reported similar experiences, for example, the ship's accountant found herself on the floor and got the hell out.
Nobody on the
Herald of Free Enterprise reported any of this, the 'terrible noise' they heard being people screaming and glass shattering, with a grinding engine.
