Assessment: MODERATE SUSPICION
Jennings was a Plessey electronic weapons engineer who died of a heart attack at age 60. While heart attacks at 60 are not uncommon, the absence of an inquest is notable given the context — his death occurred during the peak of the GEC-Marconi death cluster, and his colleague at Plessey, Michael Baker, had died just one month earlier. Heart attacks can be induced by certain poisons and drugs that are difficult to detect in standard autopsies.
Circumstances of Death
In June 1987, Frank Jennings, a 60-year-old Plessey electronic weapons engineer, died of a heart attack. No inquest was held into his death — unusual given that at least six other defense scientists had already died under suspicious circumstances in the preceding months and the pattern had begun receiving media attention.
Background
Frank Jennings was a 60-year-old electronic weapons engineer employed by Plessey, a major British defense electronics company that was later acquired by GEC-Marconi. As a weapons engineer at Plessey, Jennings worked on classified electronic weapons systems. His colleague at Plessey, Michael Baker, a digital communications expert, had been killed in a car crash just one month earlier in May 1987.
Why This Death Possibly Raises Questions
- No inquest was held, despite the growing pattern of defense scientist deaths that was already receiving media attention by mid-1987
- His Plessey colleague Michael Baker had died just one month earlier
- Heart attacks can be induced by certain substances (e.g., potassium chloride, digitalis, succinylcholine) that may not be detected in routine autopsies
- He worked on classified electronic weapons systems
- His death occurred during the peak of the GEC-Marconi death cluster
- The absence of an inquest meant no independent scrutiny of the circumstances
