Boeing whistleblowers are dying a lot lately:

• https://en.wikipedia.org/wiki/John_Barnett_(whistleblower)

• https://www.seattletimes.com/business/whistleblower-josh-dean-of-boeing-supplier-spirit-aerosystems-has-died/
  

This question will resolve YES if any court rules that foul play was involved in the death of any Boeing whistleblower.
NO, otherwise.
