I could not get the "comments" area to display, a problem I've had with Youtube for the last week or so (shows a list of other videos below it rather than on the right side).
Anyway, went to her website and entered a comment there to let her know the LES had one big 26" solid motor with four angled nozzles. Not four individual motors. Included links to two drawings.
I'm impressed at how much she does get right, posting so often with such a wide range of infromation.
As there's SO much detail to learn that is hard for most other than people who mainly research just one or two rocket types over years, or plain were exposed to if they were alive during Apollo and devoured everything available at the time (I remembered seeing video if the Q-Ball cover popping off before ignition). As opposed to a younger person trying to learn SO much about everything across the board.
