If as the IHST have stated, they want to reduced the accident rate by 80% in the next 10 years, they might want do a psychological study of the mindset of pilots who use this practice.
There are accidents due to this and we have all seen them over the years but, more importantly, it points to an attitude of mind which we might have to consider when attempting to reduce the accident rate to the extent stated above.
It is no coincidence that this practice is deemed unacceptable in ICAO Annex 6 and other more responsible regulations.
