It's also quite likely that it was already loaded in to a flight container & the container itself missed the flight, as the contents had already been approved it would simply remain sealed & go on the next available flight.
Nope. Some items made it, some didn't. It was a transfer so the items were unloaded. The problem was further compounded by the items not being stored in Brussels firearms area, they were left in general baggage. The rifle and another firearm marked baggage became separated. One was delivered, another left near the door on an unsecured warehouse.

IATA classes compressed gases as Class 2 Dangerous Goods. Not prohibited goods. They can fly when the correct processes are followed. That is probably not what RM want to do so they don't. Fair enough. But it isn't against flying regs for compressed air to fly unaccompanied or otherwise.
