As a fixed wing student, I would be at the least releived if someone came to my aid like this guy. Can I suggest a nomination to the CAA for the annual safety award, as well as the awards that various magazines run. All power to the FI, a job well very well done, and I imagine the student did learn something that day, extra to the syllabus and worthwhile.
This, in my opinion, is airmanship of the highest order and all power to the FI concerned. As for the CP, is he actually a pilot or does he fly a desk???
Awards should be given out, to the FI for such a great act, and to the CP for "Pratt of the year". A CAA endorsement of the FI's activities should wind the CP's neck in nicely!!!
