War Weary - Time Expired Aircraft

[Broncazonk]

I was reading American Eagles Vol. 4 last night and the book makes reference to 'WW' marked P-51's. At some flight hour count, these 'war weary' aircraft were pulled out of combat and transfered to operational training units. Does anyone know what the hour count was for P-47's and P-51's?

I got the impression from the book that regardless of an aircraft's structural condition, individual aircraft were pulled of the line on a strict flight hour count.

Does anyone have details on this fascinating aspect of combat logistics?


Thanks!
