With His Emergency Gas Tank Still On, A P-40 Returns To His Field. In This Scene I Was Impressed With The Tunnel Like Quality Of The Enormous Palm Grove That Seemed To Find Its Opening To Daylight In The Glittering Coral Runway. At The Roar Of A Returning Plane, Every Head Turns To See If The Plane Still Carries Its Emergency Gas Tank, Or If The Plane Does A Slow Roll. The Missing Tank Denotes Combat, And Each Slow Roll Denotes An Enemy Plane Shot Down.
