That infers more detail than currently seems available.

FWIW, I recall hearing at the time the incident involved a failed start, mixing of liquid peroxide and alcohol, and a detonation.

A google search on - phil bellmore rocket - turns this up:

According to someone who spoke with his family, he was NOT mixing peroxide and
alcohol, he was testing a rocket motor with peroxide and ethanol. He did not
die immediately of his injuries, but went to the hospital with good prognosis
for recovery but his heart stopped during surgery.

"Mixing peroxide and alcohol" was apparently a garbled initial report of the
incident from earlier in the same discussion thread.

Do you have a citation for him mixing alcohol and peroxide? I haven't
found one, and based on his experience it doesn't seem like something
he'd do. I found one 'apparently' stated by a third party, but that's
no sort of proof.

He had a distillation setup, and those are generally more dangerous
than the peroxide itself.
