And how much does that IR ship cost to keep in the air, Bose?
You can get very capable VLA/ML machines for £30k and running costs of under £25ph. The replacement engine (1500 TBO - non compulsory) is around £8000, fuel is £10 and the rest is insurance and hangarage with a bit of maintenance.
I'd factor in depreciation at 5% pa on, say a Eurostar that had already depreciated to £30k.
