Yeah, one of them should of caught it on the cockpit setup, then another opportunity as a checklist item. Then you have the event of flying into the dirt, waiting for the flight director, all kinds of fail going on.

Just parked at the gate, I like to leave the MCP altitude window set 100’ below expected initial clearance altitude, no zero or field elevation. Of course there isn’t anything required, only personal technique.

Yes, going over the departure clearance is very basic for a 121 flight.
