Let's wait for that "someone" to speak up. Why bother if (s)he does maybe
not even exist.

For that you would need METAR sets for several stations and for several
moments in time. It would have to support recorded weather for a flight
from, let's say, KSFO to KJFK. I don't see a way to integrate something
like this in fgfs.

The best we can do, is to modify the METAR system to "send" a query
to the property system (KSFO at <time>) and to expect a matching METAR
string as a response within a few seconds, otherwise to fetch the data
from the net. It'll then be in the responsibility of "Mr(s). Someone"
to feed recorded METAR strings to fgfs via telnet/socket.

Or, to make the fetch address settable, so "Someone" can set up a
webserver that delivers old data. Recording METAR strings is *very*
simple and can be done with a few lines of bash.
