Big airplanes need to oversteer, especially on narrow taxiways.

Well, not really true. First of all the virus that causes COVID19 is approximately 125 nanometers (.125 microns) not 5. Secondly, NASA quotes this study study they did (https://ntrs.nasa.gov/search.jsp?R=20170005166) that clearly shows almost 100% efficiency at .01 micron or 10 nanometers or above.

I’ve been wondering about something similar. The recirculating fans save (depending on the aircraft) if I remember right something like 80 pounds of fuel an hour or 12 gallons. Seems like not so much v running the air once through but for the HEPA filters which are supposed to take virtually everything out ...

Well, I’ve thought about that and would agree ... except. Let’s consider the financial structure of business, at least in the US as it pertains to airlines. There is this perfectly legal business strategy called a “hostile takeover”whereby the aggressor is able to wrest control of the company against the wishes of the current management. This strategy was used successfully on several different airlines in the 80’s and 90’s. Ultimately the aggressor upon gaining control can transfer value away from the airline and into their own pockets, leaving the airline financially distressed and perhaps non viable. Eastern experienced this with the transfer of assets (Airframes) literally over night to Continental, resulting in increasing seat mile costs as fixed costs had to be spread over fewer revenue producing units. Perhaps more illustrative is the Northwest story. Taken over by an “investment” group, Northwest in the day famously had no debt. However, after the ultra financially conservative m
