Sorry about the c**k up in originally omitting the date, chaps.
As regards the MoD, there has been an indication of 'bulk' attendance (presumably this relates to numbers rather than collar/bust sizes...) from DASC (the Defence Aviation Safety Centre - to quote "
an established tri-Service policy, regulation and auditing body within MoD Central Staffs that acts as the executive arm of the Defence Aviation Safety Board and is the MoD focus for pan-Defence Aviation Safety issues ").
Hopefully, this will provide for a military viewpoint.
That date again = 5th May.
