Here is a link to some cool Royal Air Force pics of 100 years ago, some of which I have selected for the 100 year thread.  Just scroll down to the bottom of the page for the aircraft/airfield pics.

PS, I didn't mention it in the 100 years ago thread, but it was on April 1, 1918 that the Royal Flying Corps and the Royal Naval Air Service in Britain were merged to form the Royal Air Force.

She noticed 10 to 15 other vehicles pulled over on the side of the road as the show took place including the lights stretching a few hundred feet and changing to red, white, and blue at one point.

While speculation abounded on her post about the possibilities -- including aliens or lights from the Mt. Holly ski hill to the Chinese satellite that re-entered the earth's atmosphere Sunday night -- the answer is a little different.

Cool story, surprised he was even able to get airborne.  Would be interesting to know if he had any flying experience, maybe in GA aircraft.

Luis Candelaria was the first person to fly a plane across the Andes, on April 13, 1918.

Interesting to see that it says he did the crossing at 4000m (~13100ft) - makes me wonder how they dealt with oxygen and hypoxia back then, or if they had any measures for it at all.

You don’t need oxygen at 13,000’. You don’t want to overdo it physically or fall asleep at that altitude but as long as you are healthy and in shape most people are fine. Acclimatization helps. I ski at 11,500 all the time and seldom even get a headache from altitude sickness.  (Usually if I try skiing the first day at altitude). People climb the peaks in Colorado that are over 14,000’ all the time without oxygen.

At what height do you need it?

Legally at least one pilot of an aircraft has to be using supplemental oxygen above 10000ft, but where you start having negative effects from altitude varies from person to person and their health at that moment.

So, is there an average height at which it's required (and not just for the one guy)?

Here's a link to the law surrounding this area and how the requirements break down in different situations (e.g. pressurised/unpressurised):
https://www.legislation.gov.au/Details/F2005B00777    - so you understand it, Flight Level 250 = 25000ft, Flight Level 100 = 10000ft, Flight Level 450 = 45000ft, etc.

Pilots require it at 12,500’ for more than 30 minutes or above 14,000’

Climbers usually don’t need it until above 15,000’

You would think that would be one area where the laws were the same in all ICAO countries, but I guess not.  ::)

When I read your reference I got the impression that it was for commercial aviation. I think the article I posted had to do with private pilots. I’m not a pilot. I was just using google to answer his question. I did get a chance to sit at the controls of a KC-135 twice for a total of about 1 hour. I have a lot of time in flight simulators. If the Canadians knew how many times I bombed the bridges around Montreal in An FB-111 they probably would not allow me in the country. I was quite good at landing the space shuttle as well. Both before and after they upgraded to the glass cockpit.

I think you're right that it's not something a visual flight rules private pilot would encounter, but it isn't making a distinction between commercial and private rather mainly pressurised and unpressurised. In Australia you often find altitudes where the oxygen carriage becomes an issue is limited solely to Instrument Flight Rules pilots, and this law is covered in their exam so they'd know about it.

Would you believe that this is one of the more clear cut areas of aviation law too?  ;D

I spent a couple of hours at the Pikes Peak Summit House which sits at 14,115 ft with no ill effects.  Of course we took the cog railway to get up there and I resisted the urge to run wind sprints at that altitude but nevertheless...

Pentagon says Boeing has been producing substandard F-15s, F/A-18s for years
Quote
Boeing Co. was cited by the Pentagon for continuing quality, management and other deficiencies first issued more than two years ago, including problems related to production of its flagship F/A-18 and F-15 jets, according to documents and officials.

Flaws at Boeing’s St. Louis aircraft production facility ranged from missing, backwards and out-of-specification fasteners found on undelivered F/A-18s and F-15s to oversized holes, missing components and incorrect parts installed on the factory’s production line, according to four “Corrective Action Requests” issued by the Pentagon’s contractor watchdog. In other cases, planes under assembly inadvertently hit maintenance work stands or other equipment on the floor, damaging the aircraft, the Defense Contract Management Agency said in a statement.

[...]

An agency synopsis prepared for senior Defense Department officials before Lord’s January meeting said that “to date, the CARs have been ineffective in preventing recurrence” of issues even after the agency invoked what at the time was $35 million in withheld payments intended “to focus and incentivize Boeing.” The company, however, “continues to display a pattern of focusing” more on actions to “maintain cash flow, increase profit and achieve contract award,” according to the synopsis.

A 737 going from NYC to Dallas had to make a diversion to Philadelphia after an engine failed and sent debris into a cabin window and depressurised the aircraft. Some choice quotes:
Quote
The crew requested a 20nm final, reported part of the aircraft was missing, they needed to slow down, they did have an engine fire indication, the crew requested medical services to meet the aircraft, they had injured passengers. ATC understood a passenger might have been sucked out of the aircraft but stopped that discussion "we'll work it out" once the aircraft was on the ground.

Passengers reported a woman was nearly sucked out of the aircraft and was pulled back into the cabin by fellow passengers

No, I just pick up the pieces when they crash, I don't fly them.
