In the simpliest possible term, a wing pushes air down.

@m4ini, you've never seen a plane fly upside down? Really? There's like a million you tube vidoes. I feel like i am living in an alternate reality.

Yeah you expert, i did. Lets see if you can see the explanation here.



Have a good look, and then explain why he's not falling out of the sky.

Tell us all how a plane flies in the simplest possible terms. And then tell us why the shower curtain is pulled inwards when running a hot shower.

Because hot air rises resulting in a low pressure zone which results in the pressure on the higher pressure side of the curtain pushing it in. Or it never happens because the system isn't tight enough and you'll get a draft on one side of the curtain.
Or because the fabric behaves that way when warming up. Can't tell you, I have plastic doors on my shower cubicle.

The UN’s nuclear watchdog has reported that Iran is staying within the main limits set down in a 2015 multilateral agreement that Donald Trump has insisted Tehran is violating.

The International Atomic Energy Agency said that Iran’s stockpile of low-enriched uranium is 88.4kg (about 195lb), less than a third of the maximum allowed under the Joint Comprehensive Plan of Action (JCPOA), the official name of the 2015 agreement. Under the agreement, Iran accepted limits on its nuclear programme in exchange for sanctions relief. The current stockpile is just over 1% of the pre-agreement level.

The stockpile of heavy water is also below the agreed limits, the IAEA said, according to journalists shown the agency’s latest quarterly report on Iran’s nuclear activities. The report comes at a critical time, as Trump has threatened to withhold his certification of Iranian compliance when he is next required to report to Congress in mid-October. He has said he expected Iran to be found non-compliant by then and “if it was up to me” would have found them non-compliant months earlier.

Former officials say the White House is putting pressure on intelligence officers and other officials to look for Iranian infractions that could justify the withdrawal of US adherence to the agreement, which is also signed by the UK, France, China, Germany and Russia.

The other signatories have said they will stick to the agreements.

“I cannot speak for the government of the United States of America. The British government, however, is fully committed to the JCPOA and to its successful implementation,” the UK ambassador to Tehran, Nicholas Hopton, said in an interview published on Thursday.

The US ambassador to the UN, Nikki Haley, travelled to the IAEA headquarters last week to press the agency to be more aggressive in its inspections regime, and to focus on Iran’s military sites.

However, Haley is not reported to have presented any new evidence about suspicious activity at any Iranian site, nor named any military base she believes should be investigated.

Tehran has been adamant in its insistence it will not allow military inspections. The government spokesman Mohammad Bagher Nobakht this week dismissed the campaign for military inspections as “a dream”.

Haley responded in a statement by saying: if “inspections of Iranian military sites are ‘merely a dream’, then Iranian compliance ... is also a dream.”

The IAEA director, Yukiya Amano, told the Associated Press that the agency has access to all locations “without making distinctions between military and civilian locations”. There is a mechanism in the JCPOA for the IAEA to request access to sensitive sites and even to compel such access with the approval of five of the eight signatories to the agreement, who are represented on a joint commission.

IAEA officials have said they will inspect Iranian military sites if there is credible information that there is suspicious activity under way there, but they are reluctant to conduct a “fishing expedition” without clear intelligence.

“If they want to bring down the deal, they will,” an IAEA official told Reuters, referring to the Trump administration. “We just don’t want to give them an excuse to.”

The issue of inspections is likely to emerge as a key battleground in the struggle over the fate of the nuclear deal. The Washington-based Institute for Science and International Security issued a report on Thursday addressing Section T of the JCPOA, which bans any development activity on nuclear weapons technology and restricts dual-use items that could be used to research warhead design. The report argues that Section T requires routine verification of sites where suspect activities or equipment might be located. It calls for a verification regimen “that includes access to military sites and the sharing of relevant information”.

Daryl Kimball, the head of the Arms Control Association, argued that the IAEA was already policing Section T.

“It’s up to the IAEA to determine what they need to inspect, and where and when, to acquire the information they need to monitor and verify compliance with Section T, and I believe they have already developed an approach for doing so,” Kimball said. “At the same time, the United States is pressing the IAEA to demand inspections at sensitive military sites in the hope of provoking a refusal that would justify a finding of noncompliance.”

Okay, mister aeronautical engineer. Why is the plane pitching like that, and what would happen if he pitched the plane level, like on "right side up" flight?

Arizona Sen. John McCain made clear in an op-ed Thursday that he believes Congress does not fall secondary to President Donald Trump — instead calling on Congress to return to regular order to accomplish the things Trump can't.

"We must respect his authority and constitutional responsibilities," McCain wrote in a Washington Post op-ed Thursday night. "We must, where we can, cooperate with him. But we are not his subordinates. We don’t answer to him. We answer to the American people."

McCain made the plea to a Congress that faces continued gridlock as it returns from August recess next week, and wrote out how it is the responsibility of Congress to serve as a check to the president's power — pointing to Trump's lack of experience in public office.

"Congress must govern with a president who has no experience of public office, is often poorly informed and can be impulsive in his speech and conduct," the Arizona senator wrote.

"We must be diligent in discharging our responsibility to serve as a check on his power," he wrote. "And we should value our identity as members of Congress more than our partisan affiliation."

McCain, who has been receiving treatment for brain cancer and has completed his first round of chemotherapy treatment, will return to Washington next week, where he's expected to lead the Senate's debate on the National Defense Authorization Act — a high priority for the Armed Services Committee chairman.

"We all know spending levels for defense and other urgent priorities have been woefully inadequate for years," McCain wrote. "But we haven’t found the will to work together to adjust them."

McCain helped to sink Republicans' hopes of Obamacare repeal this summer, voting "no" on the controversial bill after being diagnosed with brain cancer. Trump has publicly knocked him for the vote.

"Congress will return from recess next week facing continued gridlock as we lurch from one self-created crisis to another. We are proving inadequate not only to our most difficult problems but also to routine duties," the senator wrote. "Our national political campaigns never stop. We seem convinced that majorities exist to impose their will with few concessions and that minorities exist to prevent the party in power from doing anything important."

The air goes both under and over the wing. it isn't an either/or issue.

Also I don't shower with a curtain so I have no idea what this shower curtain issue is.

That's a single frame. Planes fly by simple momentum transfer from the wing to air molecules. The wing pushes the air down due to the slope of the wing and the speed of the plane, causing the plane to go up.

This is literally a physics 101 problem, basically its easy to calculate both explanations, the difference in air pressure turns out to be completely negligible compared to the momentum transfer. It's in intro college physics classes because high schools teach it incorrectly like 95% of the time.
