Penzance/Scillies AW139 G-PNZH came over this morning and into Biggin, heading towards the hangars in the SE corner, presumably Castle Air. I know the Skybus Twin Otters used to visit occasionally for maintenance - would have thought service operator Sloane would be doing the major spanner stuff at Sywell. Will be down in PZ in a month's time, not planning on a trip across to St Marys - this time any way!
