Out of interest to everyone with a negative opinion, the law in Canada (ICAO) can be found at the following link....
http://web.elastic.org/~fche/aip/AIP-01-05-95.html
It clearly states that you CAN land on the surface before the threshold, at least in Canada.
I am very interested in locating any other regulation, JAA, FAA, or otherwise that clearly states a position, negative or positive, as I can't find any.
Any help would be greatly appreciated.
