This was a daylight precision bombing mission involving 30 planes from the 6th Bomb Group:
The second combat-credited mission was flown on the 8th to bomb the airfield on Moen Island in the Truk Group. Thirty ships bombed the primary target hitting it with hundreds of 500 lbs. general purpose bombs. Enemy opposition was negligible and strike results were fair. Sixth combat crews got their first look at flak bursts on this mission, however no planes were damaged and all returned safely.
