Well I never thought such a simple question would invoke such a response.
For my two pennies worth, I have spoken with both Instructors at Heli Flight, and students, and have been impressed.
As for the accident rate, well it comes with the territory surely, the more activity the greater the risk (Ask Any Insurance Agent), and if they professed that they had a zero rate, I would raise my eyebrows.
Just as a side note, has anyone got any insights to Chesapeake Helicopters in Virgina USA, as a part 141 training facility, not that I have dismissed Heli-flight, am planning on going to NZ to get my PPL then USA to complete CPL. Would like an insight to Chesapeake so I can make a comparison between them and HAI.
