India Mike,
Both ends of the aeroplane are pointy then are they? love to know which aircraft you have been working on recently...lol! maybe a better description is "one end is hot!".
Obviously in this day and age "hot" suggests a bit dangerous, suggesting suitable "adult" supervision required. So the sooties amongst you would take that as an endorsement of their abilities. Personally as a rigger I would suggest the heat is just there as a clue to tell them which end is theirs.
Cheers m'dear, JJ
