The very last thing I teach is the take off. Fact is I let my students know the take off is perhaps the hardest part of flying.
Why would I do this you ask?? Perhaps I'm just prone to BS!! Nope, well, maybe just A little, I was taught this way too.
I don't want one of my students thinking he will fly without me being there if I'm late getting to the field. Taking off is just way too easy, flying isn't too hard but that landing thing and keeping the plane in one piece is always A thrill.
I teach flying first, landing second then that really hard part, the dreaded take off.
