Re: [meteorite-list] greenland meteor strike

2019-03-21 Thread MexicoDoug via Meteorite-list
Thanks Bob, 

The BBC article was the only sane article in the bunch. Other UK sources were 
as crazy as our cable news broadcasters.

Reporting was crazy as both CNN and Foxnews were such a jumbled mess that any 
normal person could not follow since the videos accompanying the story top 
center were old videos with a new story text below -- and one would never know, 
and more likely think the videos wer ethe new story. CNN may have just followed 
Foxnews (or Fox copied them) in that the energy CNN originally quoted for the 
new event, incorrectly quoted the prior event energy, so CNN was flat wrong. 
MSNBC appears to have gotten the story right, but sensationalized it so badly 
that it appeared it was the Chelyabinsk explosion with their old video which, 
like Foxnews, would easily be confused with the actual new event, complete with 
people running and screaming. *SMH*

I was curious about Ron because he inadvertently started the ball rolling on 
the Greenland converted Thule/nuclear war event, and last time I checked his 
Twitter it was suspended, which seemed really odd, unless he got in trouble for 
just having a personal account with his JPL credentials unexpectedly pulling 
JPL into the mix of "experts" that were sources for the latest Chicken Little 
story!

 "A fireball was detected over Greenland on July 25, 2018 by US Government 
sensors at an altitude of 43.3 km. The energy from the explosion is estimated 
to be 2.1 kilotons. pic.twitter.com/EePuk14Pqd"
— Rocket Ron (@RonBaalke) July 31, 2018

So the media then ran with him as a spokesman of sorts from JPL's Solar 
Dynamics Laboratory, after Hans Kristensen, is the Director of Nuclear 
Information at the Federation of American Scientists replied to it setting the 
stage for the feeding frenzy. For example, from 
https://theoutline.com/post/5708/what-if-that-meteor-was-aliens?zd=1=zocrn74m

"The news of the explosion appears to have originated from Ron Baalke of NASA’s 
Jet Propulsion Laboratory (see the first of the two tweets above), and 
eventually made its way to a scientist whose handle is @nukestrat (see the 
second tweet), who pretty strongly implied that a meteor exploding near an Air 
Force base almost plunged us into nuclear war. @nukestrat, aka Hans Kristensen, 
is the Director of Nuclear Information at the Federation of American 
Scientists, so it makes sense that he would offer nuke-related commentary about 
whichever news story, pretty much whenever. But it seems as if his tweet began 
a weird feedback loop in which news outlets kept wondering why the Air Force 
didn’t acknowledge the explosion in the first place, giving the overall 
impression that something super fishy was going on.

This is how conspiracy theories start in 2018, I guess — with commentary that 
quickly spirals into context collapse."

Best Regards,
Doug

Subject: Re: [meteorite-list] greenland meteor strike

Hello Doug, 
Just to be clear, I was replying in regards to Paul Gessler's post and his 
title "greenland meteor strike", making it clear that the articles he 
referenced were about the Bering Sea meteor in December and not about the 
Greenland Meteor in July, (even though the Fox "News" used an old, meteor video 
involving the military base near Greenland in July).  
Contrary to the description accompanying that older FOX video, the US Air Force 
were the first to notify NASA about the December fireball over the Bering Sea.
I just figured that Paul's post (and title) and the reference to BOTH the BBC 
and Fox "News" articles (and their stark differences) were his Canadian-polite 
way of rubbing our collective US noses in our own "do-do" that is now US 
internet "journalism". 
With best regards, Bob V. P.S. - I must admit that I have no knowledge of Ron 
Baalke's status at JPL.

 I saw the the same sensationalized story written up as a CNN report today:

"A meteor exploded in the Earth's atmosphere with 10 times the energy of the 
Hiroshima atomic bomb",

and CNN's article has buildings shaking and glass breaking on the autoplay 
video on top of the page (from Chelyabinsk).

https://www.cnn.com/2019/03/18/us/meteor-blast-fireball-explosion-nasa-space-trnd/index.html

and they even screwed up the size of the explosion (since been revised in the 
story, ironic since the title was about the energy that then needed 
correction)! 

MSNBC did a slightly longer sensational version, which was interesting for a 
casual reader,

" Meteor blast over Russia's Bering Sea packed 10 times the power of Hiroshima 
bomb"

To be fair, the BBC was a source of the report for all three of the cable
