From the late 90s onward for a few years I was flying the AC90 & 95B single crew quite literally 'world-wide' on survey ops.. Probably the best flying of my 30 yr career. Setting off alone from the UK to South or Central America through the winter arctic, Middle or Far East, South Africa.. testing at times but I learned a real passion for flying the turbine TCs. The 95B would get me up into the mid 30s.. (a real 'Airway' blocker) ATC would fall over themselves to offer me 'direct' to wherever I needed to go. Maybe the most exotic flight (among so many).. taking off from Manaus for Santarem just before midnight with huge, magnificent CBs lighting up the sky in every direction, staying (very) low following the Amazon seeing the river and rain forest lighting up in almost continuous flashes.. 2 hours that will stay with me forever.. Many other trips that pilots might only dream of doing.. A great airplane to have around me.
