I would pay money for this in the safety amusement park, but in real life way more people would get hurt operating the fake one at the airport than we'd help in real emergencies. Plane crashes where the emergency exit gets operated are so rare they effectively don't happen.

For context, "In the 2025 incoming class, this group constitutes roughly one-eighth of our entire entering cohort."

39% got this right:

    Round the number 374518 to the nearest 100 
    

    Find 13/16 ÷ 2. 
    

    If a=-2 and b=-3, evaluate ab² - a/b 

Still it's 3 to 4 cruise ships a month according to that article and, while probably hugely dirty, I would be surprised if the asthma rates of kids in affluent Greenwich and Blackheath are among "the highest in London" because of this.

Wait, what? There are no container docks in London. The nearest container port serving London is Tilbury, near the coast. Occasionally a single cruise ship moors in the Pool of London against the HMS Belfast, but that's happening only one this month, for 12 hours on April 7, according to the Tower Bridge lift schedule: https://www.towerbridge.org.uk/lift-times

The disclaimer amounts to "we're not insider trading and we really believe this stuff" many different ways. Insider trading is illegal so they are scrupulously careful to stay away from MNPI (and want you to know that). Really believing this stuff is important because if they turn out to be wrong, it's sort of ok to be honestly wrong, it's not okay to be knowingly wrong and put out the report anyway to manipulate the stock.

And so paragraphs and paragraphs of

>"Reports are based on generally available information, field research, inferences and deductions"

We're not insider trading

>"Our opinions are held in good faith, and we have based them upon publicly available facts and evidence"

We really believe this stuff, also we're really not insider trading.

> "We conducted research and analysis based on public information in a manner that any person could have done if they had been interested in doing so."

Did we mention we're not insider trading?

The battery API was rolled out by all the major browsers between 2012 and 2014 as a way to let web pages avoid doing compute-intensive stuff on low battery, but it was pretty much immediately used for fingerprinting as the battery level number was so precise that if you hit two web pages at the same time, the battery level was as good as a cookie. Firefox and Safari/Webkit disabled it in 2016 but Chrome just capped the precision at two digits.
