Great outcome. I’m a little confused about the medical issue, though. A ruptured aorta is not a widow maker heart attack. In fact, that is not a heart attack at all. A widow maker heart attack involves a blockage in the LAD artery which runs TO the aorta.  

Don't let the technical inaccuracy of the author get in the way of missing the main point to the story.

I think you mean "don't let the technical inaccuracy of the author get in the way of grasping the main point to the story."    It would be great if your little dig even made sense.  

Incidentally, I haven't failed to grasp it.  The watch clearly helped summon the medics for a very serious incident that required immediate attention. A ruptured aorta is likely even worse than a heart attack.  And for this reason, I'm interested in what actually might have happened.  I do think it matters in terms of the tech involved.

Survivability also depends on how the iPhone landed, I think it has a better chance of surviving such a fall if it hit the ground on a corner or a side. Also your not taking into account wind factor. The phone will have a better chance of surviving if there was wind to slow down velocity. 

A horizontal wind would slow down a vertical drop? That's a new one. And then you say that the faster the wind the slower the velocity when it hits the ground - that's also a new one. I won't actually argue with you because I don't believe any argument is required here. I'll just let you reconsider.

 
I'm a Part 107 Unmanned Aircraft pilot and commercial drone pilot.  I also fly fixed wing electric ducted fan jets.  Based on the above, I don't think you should be criticizing anyone.  You clearly have little understanding of how the principles of airflow work.   



1. Wind is not "horizontal."  It comes from a cardinal and intercardinal (sometimes called "ordinal") direction, but is never "horizontal" (at least for long) due to all sorts of factors, including thermals, gusts, etc.  

2. Almost any object dropped from a plane is not going to be "vertical" in its fall, either.  Even if you are dealing with a high mass, high density object with minimal wind resistance, you'll have some variation in the fall.  

3.  Putting the above aside, yes, wind will absolutely affect a falling object, particularly an iPhone.  This will happen because of the velocity of the object and the wind resistance as it gains speed and hits terminal velocity.  Like any airframe, speed increase resistance.  It also will generate some degree of lift as the object flips about.  

4.  Yes, in reality, increased wind would slow down the object's descent (assuming there wasn't a downdraft).  Such slowing could be significant if there was a thermal, gusting or rotational winds, etc.  It's not hard to understand why.  If moved "off course" laterally by wind, the object would no longer be taking a straight path to the ground.  Even if it only was blown in one direction consistently...any horizontal movement would lengthen the path to the ground.  Of course the chances of that one direction "push" are not good...it would obviously move back and forth with the wind.  

Let me put it this way...do you think the rate of descent would be slowed if it was dropped into a hurricane? A tornado? What about just a WNW 45Kn wind?  

Great outcome. I’m a little confused about the medical issue, though. A ruptured aorta is not a widow maker heart attack. In fact, that is not a heart attack at all. A widow maker heart attack involves a blockage in the LAD artery which runs TO the aorta.  

LOL.  The only thing I trust less than Facebook is the FTC.  

"Bad hardware sales figures."  

OK, this is the problem.  "Bad hardware" figures cannot equate with "some decline year to year."   As an enthusiastic capitalist, I must say that one of the problems with our system is that often, corporate value is determined by endless growth.  

Apple sells an average of 55 million+ iPhones per quarter.  That's nearly a quarter of a billion iPhones per year.  So if they sell 60 million in Q2 a year prior, a "bad" number is 58 million?  That's the headline.  The same goes for revenue.  In 2013, Apple had revenues of less than $200b.  10 years later, their revenue has doubled to almost $400b.   But somehow if Q2 2023 is 2% lower than Q2 2022, it's doomsday.
