A chopper flypast was organised for the funeral of an old SGT who was instrumental is setting up our Bushranger gunships. The flypast involved loading a few thousand blanks into the ammo bins for the miniguns, and blazing them off as the bird overflew the funeral.
The squadron CO, also involved in the original setup, was the pilot, and at the nominated time overflew the cemetery and released a bucketload of shell casings and links onto the gathered crowd below.
The radio then crackled "Our cemetery is over HERE!", a couple of miles away! When he got to the correct cemetery, there was only enough for a quick "BRRRRT" and that was it. Red face for the CO, who blamed the Pilot Officer copilot.
