boiling of the Glosters [closed]

Solution 1:

The Gloster aircraft company produced military aircraft for the British government in both world wars, in particular the Bristol F28 reconnaissance and fighter aircraft in WW1 and the Gloster Meteor the allies only jet fighter in WW2.

Depending on the period of the book "Glosters" could refer to almost any product of the company. "The boiling of the Glosters" would refer (poetically) to either or both of the disturbance of the air as the stick of planes took off or the visual effect of complex movement on the observer (compare with "the boiling of the waters" referring to waves or the disturbance of water by sea creatures, boats, or submarines). "Chased by their own din" then becomes a reference to the sound of the aircraft.

EDIT: As the book identified by Xanne in a comment was published in the 1962 the reference is probably to Gloster Meteors which continued to be produced after the war, could well have been sold to the Argentine government in the 50s and with which Conti, as a pilot, would have been familiar.
