Firstly. The A330 U/C bay is huge. It is designed for an extra gear (A340) You could get a small car in there.
Secondly. The U/C doors are not opened on a daily check and have not been since I’ve been in the industry (28 years, as an aircraft engineer)
Thirdly. Aircrew walkround……….Need I say more!

So two failures by BA, one by the engineering staff and one by the flight crew on walkround who missed a fault that seems to be well known. I wonder if the pressure of work to keep these aircraft in the air and earning money have any bearing on this?

Three. The push back crew not only have to do a final walk round check, they have to verbally inform the crew that all doors and panels are secure prior to the start of the push back.
As the AAIB have pictures of the aircraft on pushback that show that the cowls were un latched and it was daylight, I think there must be some very red faces in BA.
Hero to zero in one photograph!

OK. To sum up, Cough’s and sneezes spread diseases?

I have no idea what you are getting at

Who checks that the filters are replaced with correct ones at the recommended time or sooner if contaminated? .

The licenced aircraft engineer who signs for the correct fitment of the recirc fan filters will have checked that they are the correct part number and will also have ensured that it has an approval certificate.

Are these records available in real time to all airport health and safety experts that each aircraft makes a stop at (ideally before the aircraft lands)?.

The maintenance records can be accessed real time by the relevant airworthiness authorities so I’m sure that if health and safety people wanted to see them a quick email would gain them access.

Are there random or regular checks (using e.g. hand held devices, that do not require maintenance operations) on filters and air ducts that are made or can be made, by airport health and safety experts, that aren’t the same checks that are carried out by the airline’s maintenence staff at routine schedules?.

I’ve never seen any.

Where did this story of the paint on the nacelles come from? I cannot see that it would make much difference personally.

I have no idea…is the OBOGS system somewhat similar to these ?

OBOGS. On board oxygen generation system.
Nothing to do with the pressurization system on civilian aircraft.

This is very old news. The 146 had a serious problem with it, in fact I was nearly incapacitated TWICE on two different aircraft because of it. Speaking to the crews of both aircraft it was not an un common occurrence.
I will never fly on the 146 again.

Any conflict would start after a period of “Sabre rattling” The Flight of Typhoon’s would have been re enforced and another hunter killer submarine would have been dispatched. The Argentinians could not hope to invade faced with a flight of the most powerful airborne weapons system in that part of the Southern Hemisphere and the most powerful underwater weapons system in the area.
When the Tornado’s were replaced by the Typhoon’s The Argentinians called it an escalation in tension because the know that their air force cannot compete.
