Hoo boy, this has woken up the readers. Male ones, anyway:

Derb—Did you ever fill a model airplane with a couple of tubes of airplane glue, strap an Estes rocket engine to the back, and then light the engine?
The model airplane would shoot wildly across the ground, and then the parachute charge would ignite the whole thing in a great big ball of fire.
Talk about pyronostalgia!

[Me] No, Sir, I didn’t. And reading that, I realise what a pathetically unimaginative pre-adolescent I was.

Then this:

Derb—I’m sure you’ll get your share of “Why on earth would you do that?” emails. I think I’ll go with “Cool” instead.
P.S. All that model airplane glue may also explain one or two things, not sure.

[Me] It’s not glue, it’s cement. And I still keep a tube handy for, you know, stress management…
