Ground Event / Encounter Ground Strike - Aircraft
Aircraft Aircraft Damaged
Human Factors
I was notified that the aircraft was damaged by a tail strike 2 flight evolutions prior to our flight. This damage was not discovered on the inbound flight to ZZZ nor by me on the exterior walk-around prior to the flight to ZZZ1. Upon reflection of the exterior preflight; I still believe I saw the tail skid showing green. It is my procedure to step under the aircraft and looking rearward up the fuselage; and then to walk away from the aircraft to inspect the horizontal stabilizers. When walking around the empennage; I then rescan the rear fuselage from both sides and look at the tail skid. It is obvious my recollection is in error. As of this writing; I have not seen the pictures of the damage.I would like to see what the condition of the tail skid to have a better informed visual of what a tail strike looks like when damaged. I will also have to better distinguish between the normal streaky dirt/oil/deice fluid marks that appear in that area of the aircraft and tail strike damage.
