To make it clear, I know it is kings college hospital. Never knew the helipad was there but guessed it was for the air ambulance. The billionaire comment was silly/sarcastic as air ambulance is funded from donations, please donate if you can. Hope that none of us ever has to use it.
Ha ha, the helipad. Genuinely never noticed it before. Is it for the new billionaires of the area? ;).
