EasyJet in forced landing as ‘smell event’ overcomes co‑pilot
Sunday Times article about an easyjet fume event flight.
Note that oil fume events are now called 'smell events'...or 'odor events' in the US.

Could this be a bit like 'nut allergy'?
Perhaps a vanishingly small percentage of people are allergic to tiny amounts of contamination which have no effect on anyone else.
Or maybe their illness was engendered by something unrelated to aircraft air.
No comment re BAe146.

Have you ever owned a Citroen 2CV or a VW Beetle? How about those sheet metal boxes around the hot bits of the aircooled cylinders and exhaust connections? Yeah, they are a cheap solution to providing heated air to the cabin. Any chance of an exhaust gasket leak, or fumes from seeping oil heated at n degrees on the cylinder head actually being sucked into the cabin. "Slim to none, let's go with it. Otherwise, geez, you're talking a real costly solution."
Bypass air straight to the cabin? What were they/we thinking?

It isn't bypass air; it's bleed air from an compressor stage which supplies an appropriate pressure.
I agree with the risk you mention but there's no such possibility with compressor bleed air. On the ground you can get some re-ingestion of your own and others exhaust gas but airport workers breath that all the time.
The theoretical source of in-flight contamination is a leaking oil seal on the forward fan/compressor bearing.

This aircraft situation is nowhere equivalent to the Citroen/Beatle situation. The aircraft uses bleed air bled from the compression section of the engine. Unlike the air in the automobiles you cited, the aircraft air is nowhere exposed to exhaust air nor engine components exposed to combustion. In piston powered aircraft (and even some turbo prop aircraft) cabin air is supplied by an engine driven compressor. On 787 the compressor is driven by an electric motor. Those compressors are functionally no different than the compression section of a turbine engine and no more nor less safe.

I agree it's not the same as Citroen/Beetle analogy. But it's not at all true to say bleed air carries the same risk as air from an electric compressor. Even a minor oil leak from a bearing (or anywhere) upstream of the bleed will result in contamination
Actually, it is very much the same. The design of most turbine engines means that there is generally only one bearing where an oil leak can result in oil into the compressor air upstream of the bleed off take - which is also the case with most electric compressors.
I'm now retired so I no longer see the daily 21.3 reports, but before I retired there was at least one "fume" event on a 787, reportedly due to an issue with the electric air compressor..

That was the original design intent - but they couldn't make it work. It uses the same oil as the engine.
That I don't know - I never actually worked the 787 but I do recall reading that they had to abandon the air bearings. But as I noted previously, there's been at least one reported "fume" event on the 787 related to an air cycle machine fault. So it's reasonable to assume it get's hot enough that if there is oil present in can cause a problem.

Study necessary, cover up?
You tube video removed, why? Not much discussion on this from the airline pilot community ? Another inconvenient truth or....
Is there a cover up? This issues needs to be studied further for hard facts as the fumes affect us, and there´s not enough facts available.
Shouldn't we ask our airlines, manufacturers, unions, authorities to do a serious hard fact study, as it appears it has been kept quiet. Not to alarm, to find solutions

But it's not a problem - after all the German BFU refuse to investigate any and all fume events.

Please provide an endpoint as we know that people of all walks of life get sick everyday from unknown causes.

The problem is not the "fume events that happen an estimated 2.6 times a day".
The problem is the non-fume events that happen more frequently and don't smell but you
breath along the years.
