I assume d the white overnight thing was enough of the coloured hair falling out suddenly that the hair left shows the grey/white hair more.
Titanic - I saw a documentary about the recently.
Apparently it was a myth they were racing to beat the transatlantic crossing record - they stood no chance. They kept their speed up because they had no choice.
The shipping line were in trouble – so they were cost cutting cheaper steal and few lifeboats and another ship had been hit but a boat and the poor steal meant is was very damaged repairing put the Titanic behind production. There was a mining strike and coal was at a premium so they took on no extra.
They had set sail with a coal fire – they had two huge bunkers and coal is prone to self-ignition. They couldn’t afford another delay so sailed with it and at first stop all the firemen bar one got off which was extremely unusual and entire fire crew changed.
Took days to deal with the fire only way was to shovel it into the furnaces and unfortunately design flaw had stacked coal directly next to hull and patriating steel - it got very hot and another fire started in second bunker – so they had to shovel coal out of that as well.
The firemen and stokers reported steel buckling and there are photos showing bulge next to first coal bunker when it set off.
They were literally running out of coal – if they had slowed down they didn’t have the coal to get up speed again and had very real problem that they might run out of fuel mid-Atlantic. Any other year icebergs wouldn’t have been so far south so it was considered lower risk option.
The hull and partion most affected bits heated up where steel had lost strength.
The shipping lien lied to American enquiry – said no firemen had survived – they shipped them out straight away. In British Firemen they had to campaign to be allowed to speak then chairmen dismissed everything they said.
