Buy an old barge, park it opposite Tait modern (near to lets say Broken Wharf) have an underdeck waiting lounge and a couple AW139's and away you go!! even if it flops it would piss off these idiots based at same location!! Worth it just to see them trip over their sandals and drop their Lentil Homus!!
