TL:DR
United makes about $9.50 per passenger.
Detailed:
United Airlines Q4 and full year 2016 performance results offer a great starting point for these calculations.
We can see that United recorded a Q4 net operating income of $397 million. In the same time frame, United recorded having moved 36.023 million passengers. This gives us a baseline ...

We don't need the video evidence. Even without the footage from many angles, there is a plethora of eye-witness accounts testifying that a plane hit the South Tower.
Here's a small sample.
At that time Chief Ganci was behind me and he thought there was another explosion in the north tower and that's when I turned around and said Chief, listen, there is a ...

The Daily Mail words their claim as follows:
[The yacht skipper Nikki] Henderson's flight from Britain to the US likely produced the same amount of emissions the journey hoped to save, countering Ms Thunberg's mission
This incorrectly characterizes the net CO2 gain of the voyage, because Henderson purchased carbon offsets. Of course, carbon offsets are not ...

Although the person named existed and served in the Royal Flying Corps, the story itself is very likely not true.
First the good news. "Dattabraya Laxuman Patwardhan" certainly existed and was apparrently a member of the Royal Flying corps. The London Gazette of 25 March 1919 records his appointment to the temporary honorary rank of Second Lieutenant. The ...

Water vapor is indeed the most important greenhouse effect contributor.(Ref. 1)
It is usually not showing up in climate change discussions because mankind basically has no way of directly affecting the amount of water vapor in the air, either positively or negatively, as anything we could or could not do is utterly dwarfed by natural processes. (As opposed ...

It didn't. You are looking at a pile of snow with an airplane some distance behind it.
Source: Try Modern magazine
In the first photo, the photographer simply took a pic of a snow pile at an angle that made it look like it was covering the aircraft, which in fact was actually behind the pile of snow (and a good way off as well).

Note that the URIs of the reports by the Dutch Safety Board seem to change from time to time as apparently their website gets reorganised. I'll try to keep the links in this answer up to date.
Failing that, the main page on the investigation of the crash of Flight MH17 seems to be stable enough and the reports are all linked from there. Another option is ...

Heathrow Airport has a "dedicated website" for the planned creation of an additional runway. From the dedicated website (emphasis added):
Heathrow Today
98% capacity – Flight movements at Heathrow are capped at 480,000/year
473,000 flight movements a year (2016) – an average of 1,300 a day
Heathrow Expansion:
740,000 flight movements capacity

When trying to ascertain why timestamps seem to disagree with each other, it is often important to start with an accurate (as possible) timeline of the events being reported on
It is also helpful to keep things co-ordinated to a single point of reference with respect to time, so we'll use UTC.

Unlike seatbelts found in cars, a seatbelt on an airplane isn't there to save you if the plane slams front first into the ground or is hit by a missile.
It's there to keep you safe in the event the plane makes a sudden move or has a minor accident. This commonly happens when flying through turbulence. Sudden movements could also happen during a bad ...

Bearing in mind subsequent changes (including the 2020 phase-out currently in the works), a 2013 press release by Northrop Grumman said:
Turkish Aerospace Industries, Inc. (TAI), a subcontractor to Northrop Grumman, delivered its first F-35 Lightning II center fuselage to Northrop Grumman and Lockheed Martin at a ceremony held at TAI's facilities in Ankara, ...

The footage of the South Tower hit exemplifies several anomalies, including a Boeing 767 flying at an impossible speed, an impossible entry into the building
There is ample documentation and physical evidence of aircraft parts at and near the WTC site in the day after crash that seem improbable without there having been an impact.

Apparently yes.
There was extensive news coverage of this, which eventually points back to this ABC News report from June 1st, 2015. The report references an internal government report, which is not published on the TSA's website with other public or partially redacted reports, at least at this time.
The news story states "undercover investigators were ...

The F-35 made by Lockheed Martin is a joint venture by multiple countries; among others, USA, Canada, Italy and Turkey.
Turkey was part of the deal and they helped funding the development of the jet. They were expelled from the program after the deal to buy the Russian S-400 missile defense system.

According to Turkish Aerospace Industries (TAI)
One of the most complex structural sections of the aircraft, "F-35A Center Fuselage" is produced by TAI as a second source.
Second source means "a company that is licensed to manufacture and sell components originally designed by another company (the first source)"

Is there any first hand evidence, accessible to the public, showing MH17 was shot down?
No, nor should we expect any.
As in almost all cases, the public do not have direct personal access to evidence of the causes of an aircraft loss. For example, It is not possible for me to visit the site of the wreckage and I lack the forensic expertise to make an ...

The story is slightly less dramatic than it sounds.
The runways themselves are not being "shifted" (i.e. construction crews getting out and laying tarmac), but just renamed and signposted.
From a Livescience report
Runways are designated according to the points on a compass, and the drifting magnetic north means that they, periodically, need to be ...

No, it was flying its usual path, same as it was flying for months before the event. Here is the path of the same flight day before (a bit to the South):
Here is the same flight on 13th of June (a bit to the North):
And here is the downed plane's flight path:
It is evident that such deviations are not atypical for this flight.

I've long thought this graphic gives a good idea of the issue
The problem at an airport is variation in local magnetic declination, not the variation in location of the magnetic north pole. Due to local magnetic anomalies, magnetic compasses rarely point at any magnetic north pole.
As others have noted, Runway naming is mostly based on local magnetic north ...

To come up with the emission per child, the original source Reproduction and the carbon legacies of individuals Global Environmental Change Volume 19, Issue 1, February 2009, pages 14-20, is considering an infinite series.

Timestamps are not a good source of information unless you are really sure where they come from. They are set using the system time of the computer creating the file, which might, for example, be set incorrectly; or the program might make a mistake when creating them or writing them to the file. For a quick demonstration of why timestamps are not reliable, I ...

Yes, "do not pair" lists do exist. They were brought in as one of the responses to the crash of Northwest Airlink Flight 5719. The accident was basically a CFIT (Controlled Flight Into Terrain) attributable to pilot error, but the attitude of the captain was cited as a major contributory factor. He harassed, brow-beat and bullied his junior first officer ...

There is no reason to doubt that Churchill explicitly mentioned Rolls-Royce in the context of the quote.
A Google Books search limited to books published before 1960 returns at least four publications that feature the Churchill quote including the Rolls-Royce reference:
