I have it on good authority that army aircrew will shortly be changing to American flight suits as trials have indicated they are more fire retardant and available in a greater range of sizes.
It does however seem to make sense to only use a single set of kit, more economical however; army aircrew not allowed to wear CS 95 Fire Retardant as insufficient in circulation to support ops and training.
Seems like joined up thinking again, not!
