Ratty, come on! There have been very few incidents of this nature while the cans were different shapes, and on one DASC report just out there are 3!! (Or so.. not got the report in front of me!) It must have cost the MOD more on cancelled sorties/recalled aircraft already than it would to continue to purchase different cans for the job! It is very similar to the change in fire extinguisher design in the last few years! Why change something that works and that people understand?? It is easy to not read/misread labels when tired or at night or working in bad weather in field conditions! WHY TAKE THE CHANCE???
In my view its just dangerous.
Rant over..
