Here's another WWII version by pilots who flew 'the hump' over the Himalayas between India & China. They were in Kurmitola, India.

1. He was alerted, For a C-109;
He had a feeling, That it was the last time.

Chorus:
He busted his ass, boys, For a gallon of gas.
Halfway to China, He busted his ass.

2. They gave him his clearance At twenty-one, five.
He never expected To get there alive.

3. With fear and trembling, He got the green light,
And took off for China In the black of the night.

4. He left George Item With a load full of gas,
Climbed on his heading, Roger Able he passed.

5. Cruising along Things going smooth,
His radio compass Got out of the groove.

6. He called over Lashio For a good Q.D.M.
They said, "Steer 360 If you want to get in."

7. He steered 360 For an hour or two
In hopes of reaching Dear old Chengtu.

8. Between the Salween And old Roger Queen
He lost control of his flying machine.

9. Down in the valley, The valley so low,
A tanker is burning, See the flames glow.

(Variation of Chorus)
See the flames glow, boys, See the flames glow.
Down in the valley, See the flames glow.

10. This is the story Of a hump pilot's life:
For a gallon of gas, boys. He gave up his life.

11. There is a moral, As you all can see.
Our flying is useless, So listen to me:

12. Don't bust your ass, boys, Tezgaon's next door
The Limies will help them; So to hell with the war.

"The Hump Song" (in Notes & Queries) reported by A. S. Limouze.
The Journal of American Folklore, Vol. 63, No. 250. (Oct. - Dec., 1950), pp. 463-465. Access is Restricted

Limouze refers to a version by the Andrews Sisters the "played incessantly over the Officer's Club public address system." He also reported that the song was always rendered humorously, half cynically, never mournfully.

Some of the footnotes, number refers to the verse.
