Re: Re: "temperatures on the day averaged about 9°C."
I agree with you. If I'd been able to find public METAR data for 3rd February I'd have quoted that for daylight hours, but sadly a generalised summary for Aberystwyth was the best I could find.
Assuming the usual British temperature distribution, we can probably assume the temperature that day peaked in mid-afternoon. But as the MoD refuses to say anything at all about the Watchkeeper's flight profile, the cause of the crash could be anything.
If the MoD had lost nearly 10% of a manned aircraft fleet we'd be seeing a lot more transparency. But here it seems to be NHI, NFI.
