Roll the dice on long flights ...feeling lucky?
« on: October 27, 2020, 08:53:15 AM »
This is a little weedy and long for this short-attention-span type, but there are some dark nuggets worthy of consideration.

;D
Interesting article. Having just done a fully packed 3.5 hour PDX-DLS, it’s amazing to me that everyone on the plane doesn’t catch it. Haven’t been that close to so many strangers since March and it was not a great feeling. No after effects though even after another 10 hours to FRA ( 30 seats to myself  8) )

Ventilation is the reason air travel is not particulalry hazardous. Sitting in a typical restaurant the humity is high, the ventilation minimal and if it's standard seating, you're within a few feet of ten people. On an airplane the bodies are packed just as close, but the humidity is super-low (keep hydrating) and the ventilation is much better than you'd expect--somewhere between 30 to 50 volume changes per hour. Half the air comes from recycled cabin air that's passed through a HEPA filter, and on most jets the remaining 50 percent is bleed air from the engine compressor stage. At typical altitude the air comes in at very low temperature and under comression instantly heats to about 150F, then it gets cooled expanding into the ventilation manifold. Nothing, and I mean nothing that lives or is simply RNA with a protein coat survives that.

So yeah, turn the vent on, wear a mask, and realize there's a good set of reasons why people on cruise ships pass infections around  briskly and people on airplanes don't.

This is a very informative comment to me. So PB, just to clarify you have no worries flying on a plane during this pandemic?  Thanks

No more than going to the grocery store. Convincing my wife, however, is a very different story.

More...  Note the $$ conection between the airlines and researchers. (' Curious to know how many researchers boarded flights after the study...) I'm sure Sturgis or a political rally is bias confirmed for those who didn't get sick.

Who else would you expect to pony up the bucks to do the research?

This is another link to some reassurance about flight safety. Does it change my reluctance to fly............no.........but it is somewhat reassuring. Stay safe, stay well. Go surfing and hopefully we will have an effective vaccine in a few months. This however is not assured.

Cheers

We have flown only twice since this began.  The big planes had reasonable spacing for seating but the small connecter planes had effectively none.  The bathrooms, load areas, and common surfaces with hundreds of hands each flight are functionally unprotectable.  Passengers and crew are still in the isles so there is a lot of unavoidable contact.  To be reasonably safe it is a full personal protection situation.  I am going to up my mask and sanitizer game before our next flight and as always do a few well spaced bleach shots for good measure which is not bad with a splash of Creme de Cassis (Chlorox Royale).

The biggest gamble is whether you can actually get on, and complete, your booked flight.

We're hearing horror stories of flights cancelled, delayed, country red lists, quarantine, exemption permits requiring bribes, PCR test required/not valid/expensive/expired by the time people arrive at their destinations etc. Rules are changing daily and check-in staff are supposed to enforce them - it's chaos, and 90% of potential flights are not being booked because of the mayhem.

The Covid virus is the least of your worries.
