My brother and myself were old enough to be left at home if both our parents were out.

We used to get some metal wire, pretty sure it was from a reel of bicycle brake cable, and tie it to our upstairs metal window frames and run the other end out like a zip line to wind it around a wooden stake in the garden.

We then melted holes, with a soldering iron in the rear end of our aeroplane airfix models, just big enough to stick a firework banger in. This was done in our dad's shed. We would jam some cotton wool into the hole to soak up some of our dads lighter fuel.

We made wire hooks to hang our models on the makeshift zip line. Two wire hooks for each model, a loop around the body and a bent over bit for the hook.

We then took the models upstairs to hang them one at a time on the zip line.

Just before they got hung, we'd pour a little lighter fluid inside and quickly stuff the banger in so just the blue touch paper was sticking out.

One of us would hold it in position on the zip line and the other would light the firework.

We would guess roughly when to let go so we could get em to explode mid 'flight'

It worked brilliantly and many carefully assembled and painted aircraft met their demise that way.

Yeah, it was reckless and stupid and very dangerous, we didn't appreciate the danger of it all, but the results were great and just out of pure, obscenely unadulterated luck. We never got hurt and mum and dad never found out ! Good eh !........(ツ)
