Someone asked about Captains making extra control inputs on Airbus's
There are two similar occasions, (EI and LH I think but please don't shoot me if I am wrong) where (both in A321's where the tail is much closer to the ground than the 319/320) the FO was flaring too late or too little. Both times the training captain in the left seat added his or her own stick inputs AT THE SAME TIME that the FO corrected his or her own mistake. Both resulted in tail strikes.
I believe this has been discussed here on PPRUNE at some depth but I don't know where.
I'm not saying that Captains should not make stick inputs just repeating what has happened when the Captains input didn't go according to plan. Oh yes, one important fact I nearly forgot was that on each occasion no mention (or 'I have control') was made that any additional inputs had been made.
