Катастрофа была запланирована?

ЦитатаA submarine expert who worked for OceanGate – the company that operates the missing submersible – warned of potential safety problems in 2018, according to US court documents.
David Lochridge moved from Scotland to Washington state to work for the firm. In a BBC interview in 2017 he enthused about the mission and said it was "destined for the sea".
But less than a year later he warned his bosses that flaws in the Titan's carbon hull might go undetected without more stringent testing, and urged the company to have an outside agency certify the vessel.
He said his verbal warnings were ignored until he wrote a report and was called into a meeting with several officials - including OceanGate chief executive Stockton Rush, who is aboard the missing submersible.
OceanGate responded by firing Lochridge. The company sued him for revealing confidential information, and the submarine expert countersued for unfair dismissal. The lawsuit was later settled. Through his lawyer, Lochridge declined to comment today.
Court documents also state that Lochridge learned that the manufacturers of the Titan’s forward viewport only certified it to a depth of 1,300 metres. The Titanic wreck lies 3,800 metres below the ocean surface.

Фактически аппарат свежеизготовленный разрушить можно было судя по всему давлением на 6000 м глубине. Но контора которая собственно делала его батисферу гарантировала только эксплуатацию до 1300 м. То есть ~0.2 от максимальной нагрузки. И понятно почему – это уже под 8 тысяч циклов нагрузки. Да и вообще значение стресса ниже диапазона шкалы графиков в статье о усталостном разрушении композитов. 
Но компании оказалось дешевле уволить специалиста поднявшего проблему.
