My old CO would berate me something terrible as I porpoised on landing. It wasn't until someone said 'when the runway is all around you, look out over the nose and flare'. 'What do you mean flare'? said I. 'Pull back on the control column' , said he, and I was cured! My multi instructor used to say on landing, 'don't go and ruin it all now'. No pressure then!
