---Flying pig n. Aerial torpedo March's thesaurus & dictionary 1933 ---
is the reference MacGyver and when you click on the words you go no-place for a reason.
In ancient history the reference was checked in the reference section of a "library".
However - I realize I'm living the twenty first century and I have to adapt.
Accordenly , this link refers to flying pigs in WWI Allied trench soldier "mil-speak"
Men in the treanches speak of incoming German " flying pigs " "toffee apples "
"flying fish" "pip-squeaks" "minnies " "coal-boxes" in a easy clickable form
acceptable to "gen X and younger researchers.
Try Googling these weapon nicknames for extra credit.
The last two links are 21 st century flying pigs used on 9/11 at the WTC towers.

....One night when Kendall and I, together with two others, were over
the parados busily digging, the enemy's machine guns traversed in our
direction.
t was soon after nine o'clock when "Jerry" started to strafe us pretty generally
along the line with "minnies," "coal-boxes," "flying pigs," "toffee apples,"
"aerial torpedoes ;; "flying fishes," "pip-squeaks," -
a very mixed assortment from his stock, to be recognized by whichever
of their names you knew them......
