I recently flew on an A330, if I am not mistaken, its -KD, which has its First class mirror held by a dozen pieces of tape.
And yes, its not duct tape - they probably ran out of the duct tape as well as the High speed one. This one had something like the medicinal or surgical tape, white in color.
First aid, it sure did need!
In many cultures, a cracked mirror is an ominous sign!
