Ramp ceremonies are only held for service personnel killed on operational duties overseas.
Much of the controversy in this case appears to have been generated by inaccurate reporting in the media; it was reported that there was no official ceremony and that the families had to make ad-hoc arrangements. This is not true. There was an official memorial service, conducted by military chaplains, following which the coffins were driven through the barracks, led by the chaplains. The route was lined by service personnel from all over NI, and there were many local people at the main gates. All of this was planned with the approval of the families, and was entirely appropriate. There was no political interference in the arrangements. The procession was shown on BBC tv (in NI, at least).
There is an established process for the repatriation of bodies from NI, and it does not involve the use of RAF AT assets. A ramp ceremony would not have been either appropriate or indeed possible.
In the past, ramp ceremonies were not held for those not on operational duty who were killed by terrorist activity, whether it was in NI, Germany, the Netherlands or elsewhere. They were not and are not held for service personnel killed whilst serving or on exercise overseas. I don't believe it would be right to instigate them for deaths occurring other than on overseas ops.
