That sounds like get-home-itis. Landing
at Hagarstown was a possibility.

Quite. I said as much in a post above.

Sure, it would have sucked to go right back to where you
took off from 10 minutes ago, but it was a possibility. If
you're not happy with the weather, don't go there. You
make it sound like it was a choice between heading
to SCAPE and running out of fuel.

Not at all. I would rather have landed than taken a route into weather,
but it was odd that I'd been given the clearance not ten minutes ago,
and then told that it couldn't be implemented. It puzzled me, as it
seems to have puzzled others. Get-home-itis has nothing to do with it.
