PLEASE play nicely folks!
FWIW, IMHO, while it is surely possible, and in fact seemingly been accompliched, one million miles in a just one year, (no less year after year), is so darn tough to accomplish that it may well, even for those who truly love to fly, take the "fun" out of it!
Also, lots of radiation and cabin air to be exposed to, as well, make it somewhat of a potential health concern to me as well!
To anyone doing this incredible milestone, I salute you all!
