What does the DITCHING pb do? PHB 10.5.4
The DITCHING pb on the pressurization panel, when selected ON,
allows the pilot to close all exterior openings below the flotation
line. This will enhance flotation of the aircraft in case of
ditching. System sends a close signal to:
• Outflow valve (if not in manual control)
• Emergency ram air inlet
• Avionics ventilation inlet and extraction valves
• Pack flow control valves
• Forward cargo isolation outlet valve (if installed)

Is this also "According to CNN"?

Nope. Found it somewhere else on the internet.

Sounds like the news media is clueless as usual about aviation
matters...

So, the above is completely nonsens? The button doesn't exist?
Those inlets can't be closed for ditching?

Actually they can in most arplanes. The 'bus has one that will do the
whole lot in one go, though. Some old Brit airplanes had the same thing.
you know,in case "Gerry snuck up on us over la Manch after a jolly good
thrashing of Dresden"
