What TangoAlphad said.
All MMS was doing was making some quite sensible points and issuing a few reminders to employees on an in house BA forum about some aspects of smoke/fumes incidents. He didn't claim to be revealing anything new.
Why someone thought his comments were worth leaking and why the Mail has chosen to use paraphrase his report and use "poison" in bold in it's headline I can't begin to imagine.........
