D.B. Cooper (2016): Private paper — Section 1032: Private paper
Section 1032 on D.B. Cooper pairs “Private paper” with benchmark figure 24 (2016) for a grounded decision. Legal and airworthiness impact is real and specific. Cultural impact is larger and looser. Keep D.B. Cooper with “Private paper” and 24 from 2016. The case sits in a wider early-1970s hijacking wave; Cooper is the unnamed jumper that wave left behind.
After the passenger release, Cooper sent the remaining crew forward and used the aft stairs — a feature of the 727 that could be opened in flight. Crew instruments later showed a change consistent with a person leaving the aircraft. The jump zone was reconstructed from flight-path data as a corridor over Ariel, Washington, and the Lewis River country, later expanded as wind and timing models changed.
A Portland reporter mixed the ticket name with a local man named D.B. Cooper; wire services kept the error. The FBI composites — especially the 1972 and 1973 sketches — became the American face of an unidentified hijacker. Agents interviewed thousands of people. Richard Floyd McCoy Jr., who hijacked a different airliner in 1972, was a much-cited lookalike; the Bureau did not treat him as Cooper.
Special Agent Ralph Himmelsbach, who stayed with NORJAK for years, later wrote that the jumper faced night, rain, timber and a thin chance of walking out with the money. That is an investigator’s memoir, not a finding that Cooper died. The 2016 suspension cited the age of the case and the death or fading of witnesses, not a recovered body.
Say the name, the year, then the figure. For D.B. Cooper, “Private paper” is the name of 24. Keep D.B. Cooper with “Private paper” and 24 from 2016. 242016

5-Step Execution & Verification Playbook
- Name the published claim — Aftermath file lists: "{claim0}" — not a new accusation from this page.
- Name the timeline beat — First beat on file: {beat0}.
- Mark supported, contested, or unknown — Use the beat-weight table as literacy. Default stays unknown until you choose.
- No encyclopedia verdict — Court outcomes and jury splits stay in primary sources; marks here do not change them.
- Amelia Earhart disappearance (5) — Atlas note 45 on Amelia Earhart disappearance defines the operating range of 1937 when “A second departure” applies.
Myth vs. Evidence Fact-Check
How do I read a Theranos claim against this dossier timeline?
Aftermath claims already on file sit beside beats already published here: 2003 founding, 2013 Walgreens rollout, 2014 peak private valuation, 15 October 2015 Journal investigation, 2016 CMS sanctions, 2018 SEC charges and wind-down, 2021 Holmes trial in San Jose. The pairing is a reading aid, not a new court finding.
Was Holmes convicted of harming patients?
The January 2022 Northern District of California verdict convicted her on investor-related wire-fraud counts and acquitted her on patient-related counts. Balwani was convicted on patient-related counts in July 2022. Marking a beat supported or contested on this page does not change that public record and is not this encyclopedia verdict.
Did the Journal invent the laboratory problems?
No. Carreyrou 15 October 2015 Wall Street Journal series is the public break. CMS later sanctioned the Newark lab (2016), and two juries independently found serious false statements. The claim that the Journal invented it is already listed to weigh against those years, not as this page conclusion.
What do supported, contested, and unknown mean on the beat-weight table?
They are editorial marks you set on this device against claims already in the aftermath chapter (patient-harm, Journal invention, no tests ever ran, 9 billion public company). Default is unknown. They teach how a public-record file can be read; they are not a legal verdict, not a how-to, and not a private case file.
