Typhoon or Tempest Pilot's poem – Snapper will like this

On the 2002 Warbirds over Wanaka DVD, new Zealand fighter pilot Jack Stafford recites an excellent poem which he said he saw on the wall of a pub in Staffordshire and memorised because it fitted his squadron (486 NZ Sqn on Typhoons and Tempests) so well. I don’t know the author or title. It goes

And now to keep a date with death
To sit and watch with baited breath
To see the tracer in the sky
Come creeping up and flashing by
The Sabre roars with iron lung
The cannons speak with jagged tongue
And death goes hurtling on its way
To stalk the earth at break of day
And if per chance the song should be
A prelude to eternity
I ask a moment’s grace that I
May think of thee before I die
That my last breath may breath thy name
Kindle while the dying flame
And all the glory of thine eyes
May live for a moment in the skies
