Thanks Chris!If the leaks were more severe, wouldn't Endeavour either lost an engine during the ride up hill (RTLS, TAL, ect) or and RSLS abort on the pad or could it have preformed nominally still?
Not good, even had one usually undramatic engineer using phrases such as "we dodged a bullet".
"As a matter of fact, the total leak rate on the nozzle from all these leaks is so small that it's not even the equivalent of one ruptured tube. They are tiny. The total leak rate in the 340 hot wall leaks that we have is 0.6592 pounds per second. So it's not even equivalent of one tube rupture, nothing you could see in the ascent performance going up hill at all."
...the anonymous engineer's comment seemed out of place with Cook's account.
To be clear Chris, I'm not criticizing you or your including the comment in the thread (and I would commend you for keeping the comment out of the article but that would suggest that you made anything but the obvious choice). Rather, I was only contrasting the comments by the "undramatic engineer" with Cook's...
That loss rate would have resulted in somewhere around 300kg of additional LH2 being used during the ~510 seconds flight to orbit, which represents somewhere around 35-40% of typical reserve LH2 on a normal Shuttle flight.
