#1 Launch was scrubbed this morning due to a high pressure indication at ignition from engine #5. Next launch attempt will be Tuesday at the earliest. Engines shut down automatically 1 second before liftoff.

#2 Number 5 engine. The center one in the cluster had an over pressure. There are 5 rockets in this series. The Falcon 9 ver 1.1 has a different engine arrangement (an octagon with one in the middle at a lower height instead of the current 3 rows of 3). In addition 1.1 has %50 more tanking and more powerful engines.
Speculation is that the over pressure comes from the neighboring engines firing and creating a back pressure. Abort was after T-0 with the engines already ignited.

#3 Turns out it is a bad check valve somewhere in the number 5 plumbing. It has now been replaced and is being tested.

Rantburg was assembled from recycled algorithms in the United States of America. No
trees were destroyed in the production of this weblog. We did hurt some, though. Sorry.
