Ok - the list so far.
1) A300 (the Vincennes incident)
2) UK Warrior AFV's in Gulf War 1
3) 2 UH60's at the end of Gulf War 1
4) Canadians on a training exercise in Afghanistan
5) 1 UK aircraft
The phrase 'bumbling amateurs' springs to mind. All the toys in the playground without the ability to play with them properly.
