Re: V22 Osprey
Nick, how to generate a statistic is entirely in the hands of its creator. However, it is important to ensure that everyone using the statistic understands it fully. I don't think your $2 million minute will be well understood after a few iterations along the grapevine.
For example, consider a comparison between a $40 million helicopter and a $100 million Osprey, which has had its initial 200nm flight. The $60 million difference was paid for at $2 million per minute. Now however, with the difference gone, the V22 is faster with the only cost of that speed being the increased incremental costs (ie fuel, maintenance, etc).
Another way to look at it is if the first flight wasn't 200nm but was 400nm. Then the V22 comes in at the cut rate price (50% off) of $1 million per minute.
Either way you run it, those numbers are just shocking statistics that aren't based on any business sense. Nobody would buy a V22 for one flight, and nobody would spread the initial purchase price completely over a single flight.
