Pegasus

I saw a plane coming from Lisbon flying high,
It was a clear night sky; I could see a horse flying
besides the plane “did you see that” the first pilot said,
to the second pilot. Yes, it was Pegasus delivering books
to those who cannot read.
We are coming back; something is wrong, the pilot said,
The chief pilot lit a cigarette, which is not allowed,
the second officer objected it was not legal.
When the plane was ready to fly again, it had another chief pilot
the second officer had reported the old one.
