When I was working there it was land at East Brighton park and ambulance transfer to A + E, for both H900 and HMCG. H900 pilots seemed to think that the car park outside A + E (RSCH) would be plenty big enough but not many escape routes if it all goes wrong and the consultants would have to walk a bit further. That was before all the building work they ve done now... maybe roof of one of the new buildings would work? Long walk/run to A + E thou.
Guess also depends on whether using police or hems AOC?
Seem to recall that those types of transfer were a regular occurance too...
