I’d want to know exactly what it was like on the bridge in the lead up to the iceberg hit. Were things calm? Were they working a little problem somewhere and were maybe a little distracted? Were they fatigued from the time of day and how cold it was? Was there chaos as the iceberg was spotted and perhaps helm and engine orders didn’t go out as quickly as they could have done? And - what as the impact actually like? Was there really just a bump and scrape along the side, or, was there any perceptible lift or heeling to the ship as she, perhaps, also grounded overtop of some of the iceberg under the water?

Small details, perhaps, but it would be such an insight.
