A rather remarkable fact has come to my attention in the last few days- the MRA4 actually has less protection than MR2. MR2 has a nitrogen inerting system in the AARprobe to prevent a possible explosive situation developing due to the presence of fuel vapours. I understand that this sensible safety feature has been removed in the MRA4. Presumably, someone thought it a good idea to save a few more pennies?
