Slightly drifting off topic, is RAF Northolt the UK "HQ" for Netjets Europe? I regulary see NJE flights operating from here outside of published opening hours (for non-military flights) & the only way to 'get around' these opening times is if they were based at Northolt.
I've also noticed that London City have had a larhe increase in NJE flights since the 125 was approved for City ops.
Back on topic, Falcon 2000EX CSDFF used Harrods when it passed through Luton a few weeks back on delivery to NJE
