Barnsey was the best pilot I knew.
I bet most aviators on here have encountered cloud at some stage in their lives, and have usually done a 180 to remain clear. Pete was IFR rated so he had the experience to fly in cloud.
London has numerous cranes going up. I think the problem with the obstructions in London is nobody is controlling them enough.
No cranes should be erected without the CAA being involved from the start, and ATC should be made aware of every one in their area (each day). Part of a hand over brief to each controller for that patch. Not just the Notams.
Do ATC have any crane obstacle markers on their screens for the London area for low level ops?
If the cranes are close to heliports such as Battersea, ATC should look at altering the heights allowed within ATC zones.
The crane type involved is becoming more common and they are almost invisible against the tower blocks in London.
Just noted the BB comment, and all I can say is weather changes...
