It wasn't unknown for many types of aircraft to visit Machrihanish on 'fish runs'.
A significant number of freshly-frozen dublin bay prawns and lobsters could be stuffed into Hunter sabrinas in poly bags....then transferred to a freezer back at home.
Except, that is, for the d***head who flew back in the summer of 1976...
...at low level. On removing the sabrina access panel, he found a warm and rather soggy poly bag full of partly cooked sea monsters....
A fish run I heard about was in the early 1950s when a MOTU Lancaster flew down from Kinloss to Merryfield. The resident Vampire pilots watched interestedly as the mighty beast hopped and bounced its way down the runway, before taxying back to stop by the tower. The crew door opened and a sack was handed over, then the Lanc took off and flew back to Kinloss.
The sack contained fresh (ish) Speyside salmon for the Officers' Mess Summer Ball!
