The excuse of President Abomination to not stop air traffic between West Africa and the United States is we need to be able to deliver supplies and medical help and personnel to these nations. This is true.
However, there is absolutely no reason not to limit these flights to essential needs only with no exceptions. Upon return all the passengers on the aircraft will be put in quarantine for 21 days with the exception of the aircrew. The aircrew is to remain on the aircraft until it is serviced and turned around for the flight home. This would require two Captains and First Officers.
Contact between crew and passengers on the return flight are to be minimal. Feed them sandwiches that are prepared in the USA prior to the flight to West Africa. Upon return to the USA all waste from the plane is to be treated as a bio hazard material. A few gallons of clorox in the waste water will take care of this all other waste will be bagged and burned. Wipe all surfaces down with disinfectant. Park the plane for 6 days with ground equipment keeping the temp in the aircraft elevated to about 90 degrees and with a very low humidity. Any viruses that the disinfection missed will die.
I would suggest these flights be done by the military.
Any person that is from West Africa coming in on a flight from Europe would be banned from entry.
Seal the Southern Border with Mexico to stop illegal immigration. If this is not done all the above precautions are irrelevant.
Sterilization of the Reston Monkey House with formaldehyde and high temps for three days did not kill the Ebola virus.
