I got concerned that the override/jettison pumps were the only way to get fuel from tanks 2/3 to the other engines.
Jack's a dull boy, GS-ALPHA, Danny et al. have rightly pointed out that the fuel left behind by the override/jettison pumps will still get to the remaining engines.
Examination of the
fuel system schematic -- something I should have done first -- shows that the boost pumps in any tank can feed any engine.
Thank you, gentlemen, for the information -- I learned something.
