My better half spent many years as an environmental scientist. She long ago questioned me on the topic of how I earn a livng, but when she dioscovered how much fuel even a large corporate jet burns, and the low utilisation of the aircraft, she realised that it is a totally insigificant amount compared to taking hundreds of families to the Costa Brava for their summer holiday.
So no, I don't find use of private aircraft for more efficient use of the time of people who have the capability to make a difference a sickening hypocrisy. I do find it a sickening hypocrisy when they come out with all sorts of grand targets for the press conference that are then completely ignored in reality.
