747 and the air is a hundredfold the energetic ferocity of a
hurricane.

intercom to fasten their seat belts because it is going to be
a little bumpy, the plane travelling at 10 times the velocity
of a hurricane may be about to pass through vertical thermals,
one outbound from the Earth at 100 miles per hour, the other
inbound toward the Earth also at 100 miles per hour. The
stresses the 747 endures going through opposing thermal shears"
