Your Plane

From some card you constructed a dart,
It resembled a bus from the start,
With miniscule wings, a number of things,
Could go wrong, and they did, I'll impart.

You launched your plane skywards with force,
It returned very swiftly of course.
Its construction was lacking in grace,
Whilst at falling it clearly was ace.

Your plane fell to earth at high speed,
T'wards a spectator who'd taken heed,
He'd stepped out of his way to observe,
But unerringly at him it swerved.

It landed atop the man's head,
Then unravelled, it has to be said,
Until once more your dart was just card,
That moment at which we laughed hard.
