Hi all!
I'm looking for help with translating a pilot's prayer from English to Irish Gaelic. My boyfriend has just completed his third and final deployment to Afghanistan with the US Army. He is now transitioning to non-military life as a pilot. I am doing this for him and for one of his Christmas presents.
All that said...
I have tried to do a rough translation on my own. And when I say rough, I mean I was flying blind with all of my translations and really have no idea if any of what I wrote makes an ounce of sense.

I'll include the original version I am trying to translate as well as my attempt at translation. ANY help would be greatly appreciated.
Original version by Mary C.D. Hamilton
Lord, guard and guide the men who fly
Through the great spaces of the sky.
Be with them traversing the air
In darkening storms for sunshine fair.
Thou who dost keep with tender might
The balanced birds in all their flight.
Thou of the tempered winds, be near,
That, having thee, they know no fear.
Control their minds with instinct fit
What time, adventuring, they quit
the firm security of land;
Grant steadfast eye and skillful hand.
Aloft in solitudes of space,
Uphold them with your saving grace.
O God, protect the men who fly
Through lonely ways beneath the sky.
Amen.
Now, here's my butchered attempt.
A Thiarna, garda agus treoir a thabhairt do fir eitilt.
Trí na spásanna móra an ar spéir.
Bí leo eitlit trían aer,
Trí stoirmeacha dorcha nó aonach gréine.
Tá tú a choinneál le neart milis
Na héin chotthromaithe i ngach a eitilt.
Tá tú na gaotha éagsúla, le do thoil a bheith in aice,
Sin, tar éis duit, tá a fhios acu aon eagla.
Treoir maidir n-intinn,
Cé t-am, iniúchadh, scor said an t-urrús daingean talún,
Sú thugo daingean agus lámh sa tír a dheonú.
Ag eitilt i an uaigneas spás,
Seasamh iad le do ghrásta a shábháil.
O dhia, a chosaint na fir a eitilt
Trí bhealaí uaigneach faoi bhun an spéir.
Again, ANY help would be appreciated.
Thank you.
