It has come to my attention from Joshua Shroyer that John Blacet passed away on June 22 after a battle with cancer. There is a thread on his passing at Muff's as well. The news comes as a bit of a shock. The last email I received from the Blacet newsletter was dated June 19, with only "Sorry, closed for now.....". I thought this was in reference to the latest sale. The email I had prior to this, dated April 18, was for a Rak-3 sale. There was no hint of his cancer or condition. John was extremely private. He reached out to me back in October of 2017 for a banner on the site. He continued the banner through December of 2018 and then just kind of disappeared. His communication was always brief and non personal. I respected that and I respected his privacy.

The following is from the front page of his website:

Apparently John was also into planes. The following is from a thread on taptalk mentioning his passing on June 22:
"John Blacet passed away June 22 at home in Lakeview after battling cancer for a year.
John was an early Sonoma Wings member who flew with us locally, in Nevada, Idaho, and the Owens Valley.
He made the first Sonoma Wings web sites.
His Atos B was for sale on www.cloudbasecafe.com and his family hopes the Atos and trike will find a good home.
