Thankyou, Pagan and imawswami,
for your insightful answers.
Obviously, I hadn't understood what "porpoising" was all about.
I have two subjective reactions to your replies:
A) I have a renewed appreciation for the engineering concepts involved in the Stratellite and similar projects.
B) Yet again, I am impressed by the depth of knowledge and command of information brought by the membership of this board.
With respect to B), we in large part have Rocky to thank, for without his skill, knowledge, and vision, this talent would not have reached a "critical mass". Many thanks to mide for stepping up to the plate. His leadership is already evident. I have faith that this board will remain the go-to site for GlobeTel information.
