no, I was not. There is an extraordinary range of expertise among cross-bench Peers, very few of whom are there because of any family privilege. Many attend only when there is a Chamber or Committee debate on which they have relevant expert knowledge, frequently greater than that of a Minister or Official. Bills are often usefully amended thereby, which is one reason why Lords Amendments are often accepted by Ministers in the Commons.

Very remiss of me, I have edited my original post. Tongue was firmly in cheek, I would much prefer that we still had a full house of hereditary peers and appointed experts [and I stop here so I don’t get barred for political posting...]

Unsurprisingly, Flyer gave a more competent summary of the AAIB report, along with a link to it.

Some fascinating info there in all areas, and I came away having thought a lot and learned a lot, as always the danger of assumptions!
I was intrigued at the way certain I imagine highly commercially sensitive parameters for the fuel cell were redacted.

Couldn't they have done their tests in a less expensive aircraft?

An old nail piston Malibu is hardly an “expensive” aircraft given the constraints of the mission.

For what they were doing, and compared to the cost of developing the powertrain, the aircraft looks pretty inexpensive to me. I doubt that the airframe cost as much as 10% of the overall project, and likely rather less.
