Narrative:

Captain/PF called for flaps 30; I verified speed and didn't put flaps down. Both captain/PF and I confirmed flaps 30 green light and landing checklist complete. Aural warning. Switched flap warning inhibit. Deemed stable; in VFR conditions and in a safe position to land and did so. I can only guess that I must have been distracted prior to putting the flaps in the final 30 position. Always verify flap position with indicator.
