Regards to Nick Daniel
After upgrading to multi-IFR in 1985 I took some aerobatics to sharpen my flying skills. Nick Daniel gave me several sessions in a Decathlon from a local Toronto airport. Of all the different types of flying I've experienced that was by far the most personally rewarding. Some time at the start included practice dumbell (dogbone) touch-and-gos at the Sifton field north of the airport --not bad considering that we did downwind takeoffs over a cliff at the end of the runway, dropping into a gorge to pick up our flying speed. We flew in all legal weather including moderately low ceilings and I learned the art of very tight loops while staring at swimming pools down below [similar to the copilot in Flight: "Oh God all I can see are houses!"]. Nick's deft touch was always apparent and he made an excellent instructor. If he's still with us, my best regards to him.
