Indeed, the low V1/Vr of 112kts should have rung alarm bells! I seen to remember from my A320 days at LTN that the Vmcg/Vmca was around 115kts, but surely the giveaway should have been the aircraft registration on the load sheet handed to the captain. Yes, a good SCM should have flagged the unusual distribution to the pilots, but no more than that. I'm afraid the fault lies firmly with the dispatcher and the pilots.
a narrow squeak!
