Moderators,
Under the alternative engine section there use to be a line of threads discussing the Honda aero engine. Now they're gone. If you use the search function then you'll find them. They seem to be hiding somewhere.
Make sure you're in the Alternative Engines forum (http://www.vansairforce.com/community/forumdisplay.php?f=22) and look at the bottom of the screen. You'll see a 'Display Options' section. You probably have the 'From' drop down box set to a value shorter than the length that thread is up. Set it to 'Beginning' and I bet it'll show up.
PS: You can set your 'UserCP'/'Edit Options' value to reflect this over all forums.
