Wasn't the weather forcast calling for a storm with 80-90 mph winds at surface level at the precise time they were up there?
They simply should have been far better prepared to attempt to summit at this time of the year. The notion of a high-speed, low-drag approach is unreasonable at this time of the year. One needs plenty of clothing, water, food, shelter, fuel, batteries, and communications capability...especially in the winter. I feel very sorry for them, at the same time, they were making a very risky gamble and lost.
