Author of soaring poem ?

Hello all.

I am trying to find the author of this soaring poem.

I'd like to use it in a presentation but want to credit the author.

The metal wings dates it somewhat.

Thanks....dave.

Once more I rise
up to the sky
to greet the clouds
to say goodbye

The glider thrums
she tugs the line
as eager for freedom
as I for mine

Looking left
I find the lift
circle tightly
my ship is swift

Here we dance
where few humans ever fly
smiling, I join the birds
I join the sky

Sun glints sharply
from metal wings
and in the silence
the glider sings

And my last words
to those below ?
"Off tow, off tow, off tow".
