Chuck / FFF - as usual, what we have come to expect: quality posts, not always saying the same thing the same way, but educating the Forum and provoking contemplation in the mind of the reader. Well done to the pair of you!
On a lighter note, from today's AvBrief:
Student pilot to irate instructor:
"You're simply impossible to satisfy. I just finished navigating successfully through a boiling fluid swirling around a rotating sphere that is hurtling around a fusion reaction source at thousands of miles per hour. This system is moving in a circular motion around a black hole at who knows what speed, while the space it takes up is expanding. And then I bounced the landing six inches. SIX MEASLY INCHES! Get off my freakin' back!"
