We have recorded data on oxygen saturation on actual jumps from 41,000' and 15,000', both in the aircraft and in freefall. The jumpers from 41K have a higher oxygen saturation with their supplemental oxygen than the jumpers from 15K without supplemental oxygen. To my knowledge, we are the only ones to record such data. Actual data and experience trumps theory and speculation. We will continue to record such data. Our systems, both onboard and freefall, provide much more oxygen than is required by the generally accepted formula of 1 LPM per 10,000', and we check all the systems with a flowmeter prior to each jump.

So Kari Lake lost her election, then she lost her lawsuit trying to stop her opponent from taking office. Hobbs then sued Lake for a frivolous lawsuit, but the judge disagreed that it was frivolous, since she found one expert who agreed with Lake. Here's the headline of the Western Journal about that: Kari Lake Scores Legal Victory, Torches Katie Hobbs' Dirty Trick I guess they need _something_ to make them think they are owning the libs.

Robert H. Edwards's Blog: Great 20th century mysteries December 30, 2022 D. B. Cooper and Flight 305: diatoms "This raises the possibility that if the $20 bill, after its discovery, had ever been washed or rinsed in river water or even tap water, it could have acquired the diatoms that were found in 2020. In my Chapter 12, I wrote that I had needed to assume that the bill and the diatoms had not met up in this way. " "In my mind, therefore, there is no reason to exclude the arrival of the money in some Northwestern waterway on the night of the hijacking." I read Edwards saying he does not support conclusions TK has made regarding diatoms found on Cooper money. I read Edwards as saying TK's diatom research is not comprehensive or correct in that it does not consider all of the options available in the diatoms-money matter. Edwards asks if diatoms on the money could not have come from tap water in the Ingram apartment washing scenario, vs exposure to Columbia river water at Tena Bar ! In other words TK's controls are lacking and do not warrant the conclusions TK made. *In other words: when is a diatom a tap water diatom vs. a Columbia River diatom ? And precisely where was Cooper money exposed to - diatoms ! TK has failed to identify the source of Cooper money diatoms and when TK says 'the money was buried in the Spring based on diatoms' - TK's research does not prove that conclusion !

Four tweets from Mr Santos over the course of a year. Bolding added. =============================== A quick correction for you. I was infected with Covid in February 2020 and tested positive at Elmhurst hospital in March 7th there was no pandemic then. I was caught my surprise and took this plague serious very early on. Plenty of media to prove this. Also true story and you can google it, the day I went in to get tested at Elmhurst I was tv in the isolation ward DeBlasio and Pelosi were telling people to go to China town and to the movies, "it's no more than a common cold" they said. That was March 4th the test date. I can't step out since the 9th of March since I became sick and tested positive for Covid19. I had it myself and can guarantee (tested positive) you that I was very sick from March 7th to March 14th. Funny thing though is that my fiancé living inside the same 1600 sf apartment did NOT get it! So yeah I think it's pretty exaggerated. The numbers don't add up! ===============

I don't know what more infuriating. The idiotic propaganda that is being spread by the 'alt-right'... Or the fact that so many fools fall for it.

The bulkhead door could definitely be locked from the outside. They would often leave these planes overnight on the tarmac with the aft stairs down. That tells me that they must have had a way to lock the bulkhead door to prevent thieves or whatever. It may have been literal keys because I believe there were actual keys that could unlock the stairs from the outside. Perhaps the same set of keys unlocked both?

Strange.. in 1996 after the Cooper Vane.. and it opened 2 ft.. https://www.spokesman.com/stories/1996/jan/18/twa-jets-door-drops-open-at-35000-feet/ A stairwell on a TWA jet popped open during a flight, and a crew member with a tether around his waist to keep him from being swept out had to pull the hatch closed. None of the 72 people aboard were hurt. The Boeing 727 was flying at 35,000 feet, at least 100 miles from its destination of San Antonio Tuesday night when a cockpit light indicated the rear stairway under the tail was open. The crew discovered it had dropped about 2 feet. A bulkhead door between the stairway and the passenger compartment prevented the cabin from losing air pressure. The captain took the plane down to 3,000 feet to permit a crew member to reach behind the bulkhead door, grab the stairway handle and pull the stairs shut, said TWA spokesman John McDonald said.

Who suggested you start sliding your landings? An instructor? I somewhat doubt that. Sliding is actually a pretty advanced technique. Its usually used when the forward speed is faster than can be run out. Tandems often slide in because they can't run and a PLF would end up with the pair rolling on top of each other. You need to have your flare dialed in pretty well. You need to stop your descent at just the right height, get your feet down gently and keep adding toggle to the flare to slowly add weight as you lose speed. Any mistake will be painful. Any irregularity in the ground (holes, ruts, bumps) can also be a problem (see below). If your ankles aren't in good enough shape to handle the impact of landing, or the stress of running one out, then learn to PLF really well. You can go from 'feet touching' to 'rolling onto your hips' with very little stress on your ankles. I'll slide in sometimes, usually when the wind is really low. Jumps early in the day are prime candidates. The morning dew on the grass also helps the sliding. But watching the ground is vital. I was coming in, planning on sliding, and just as I was about to touch, saw that there was a pretty deep tire rut in the grass ahead (maybe 6"deep). If I had slid into that I likely would have broken something. So I PLF'd it. A couple grass stains and a bit damp from the dew, but that was it.
