Indeed, it's the minute detail and the comprehensive re-fit (insisted-on by CAA) which has allowed the programme to take so long and become so expensive.
OK Tim, so it's the CAA's fault then? So you fully understand how this works from your extensive dealings with them? You are conversant with the regulatory regime? "Permit to Fly" does not mean it can be treated as a light aircraft. Because it is not going to carry passengers does not mean it is not a commercial undertaking and the aircraft is not going to be involved in "Aerial Work". The regulations applied by the CAA are in place to ensure the safety of the public and the operators, which ones do you propose to ignore Tim?
