Good post. Yes some of us on the particle team including myself currently believe that powdered metallurgy may be our best explanation due to the touch transfer, particle size and opportunity to produce Frankenstein particles like 14 iron heavy ones that have been flagged and very difficult to alloy metal combos due to vastly different melting points as well as other factors like the TiSb. The team recently found that the average area of the metals on the tie fall loosely into the expected size you'd see in powdered metallurgy 25-130 micro millimeters. We currently have stub 675 from the tie knot at Mccrone undergoing a very thorough rescan so we should know more soon!

Yesterday I became one of only 33 non licensed skydivers in the world to have jumped a passenger jet. Blue skies! https://skydive.shredvideo.com/f/77ZJE6xB40

From TK: Stub UPDATE! I am happy to report that stub 675 which is from the tie knot will be delivered to McCrone this week. 675 should have lots of particles that came from his finger tips and holds the most unusual particles like the titanium antimony. I decided that we should go full bore on the best possible stub and told McCrone we want longer dwell times on each particle and go to the max on the number of particles to analyze. McCrone has assured us that the techniques they are using today are far more advanced than what we used back in 2017. We are expecting to get better analysis of particles we know to be on the stub as well as many never before seen particles. McCone said they have a "window" right now and should be able to get it scanned sooner than later. Myself and the rest of the particle team are anxiously awaiting the results and we will keep you posted as new things emerge. Unfortunately we will not be able to confirm the new particles until I get back to my lab beginning of October so lets keep our heads until final confirmation happens. New data! Exciting times!

An experiment Chaucer did a while back would suggest otherwise. This was 24 hours after bath tub submergence.

Help me jump a jet! https://gofund.me/2b216231

I was considering but it’s gonna be hot AF in July. I’d rather be comfortable and enjoy the jump!

I did and was over the moon when I heard they will be doing tandems from the DC 9-21 the weekend of July 6th and 7th. I’m going to get the chance to jump a jet!

Hi DM! Indeed I did. They are sending multiple loads up tomorrow so I’m planning on swinging by. I will see if I can find out if it’s going to be a regular thing or not. If it is then it’s definitely AFF classes for me this summer at Elsinore!

This is a link to a Go Fund Me account being set up for a re-scan of tie particles. Through Tom's goodwill and McCrone Labs' interest in the case, McCrone has agreed to do a re-scan of one of the tie stubs for only $500, which is essentially at cost for microscope time. We are setting up the account for up to $1,500 for the possibility (no guarantees) that McCrone might agree to re-scan an 2 additional stubs in the future at the same cost. A re-scan would provide x-y coordinates with a true "north south" orientation that would allow Tom to look at specific particles of interest more easily and definitively. Thank you for your consideration. update: McCrone has agreed to run a total of four stubs for us at $500 each. https://gofund.me/7a65d011

I came across him he was one of the pioneers of the sport along with LC but nothing to connect and a marking on his chin.

Are you back at Elsinore?

Merry Christmas to all my cooperites!

You are entitled to that opinion. We will just have to agree to disagree here fly. At any rate a Merry Christmas to you sir. Keep Digging! Nicky

His reply “lol that is exactly what we’re doing. Consider it a gift if you can pin a particle down to a specific time and place. I would argue that’s probably less likely with a “registered, alloy”, because those have greater adoption and are used in more places.”

My metallurgist says: “What. Of course you can!”

From my metallurgist: “Registered alloys” is still a red herring. Don’t focus on that. Readings with elemental concentration of greater than 1% are perfectly fine even in the automated EDS. With the possible exception of Ni in this specific test.

From my metallurgist: “All automated EDS is a bit sketchy. Especially so if it can’t be checked against a calibrated standard, like here. I would definitely assume that any Al-5Mg particle is a 5000-series Al alloy whether the database is showing me more elements or not. It might also be helpful to reel back a little bit and think about what is meant by “alloy”: a metallic mixture of two or more elements. It needn’t be homogeneous (eg nickel superalloys), and it can include nonmetallic elements (eg carbon in steel)”

Actually only 39% of particles that are Al#1 and Mg#2 are only those 2 elements (187 out of 482), while 61% have a 3rd or 4th element (295 out of 482). Table courtesy of Chris Broer.

Happy Thanksgiving to all my Cooperites!
