Sorry to hear your dad has taken his final flight. He will truly be missed. Deepest Condolences.
“...Not looking back to ask the reason why
Our plane is set along this course,
Gladly we shall go, unsullied by remorse;
Nor blaming now the mundane evils of the past
Or that idolatry which planned our flight; we die
To live enthroned forever with the fold
That dwells immortal in the Halls of great Valhalla.
Long-dormant Viking hearts awake at last -
We take in hands as bold as those of old
The helm of our own destiny; and for our vast
Ocean of adventure, instead of waves, the boundless sky.
Once more, inviolate, erect and proud
As those who never down to tyranny have bowed.
On wings of valour. Woden-borne, we fly. “
(Wings of Valour - Anon)
I am sorry.
That’s a tough road to walk.
