Two more questions if I may:
1) The aerial (HF?) running to the tail skid; did it then run up the other side. ie was it overall 'V' shaped or a single line?
2) Regarding the parked aircraft. Are there any static covers, blanks - flags etc that 'would' have been fitted? Likewise can I assume that tip sock fitment would have been weather (wind) dependent at the time and therefore no being seen it not a deal.
Artistic License only goes so far and it is frustrating at an Art Exhibition to have your pride and joy ripped to shreds on minor technical matters.
