Known bug: the "View Page Stats" graphic link below results in a "Can't find this page" error. A message was sent to Yahoo Geocities tech support on July 21, 2008. A reply from Emily via Yahoo email was received July 22, 2008 with a request for more information on the problem. Clarification was sent that day. Apparently the bug is a difficult one to track down because it's still not fixed as of the update date for this page (see below).

Lunar Lander Applet

This applet is a physical simulation of a variable throttle lander in lunar gravity. You must land at two meters per second or slower to avoid a crash. The default starting throttle setting is 50%. As fuel is consumed, mass decreases, making the throttle touchier. Consume all the fuel, and it will flame out. Fly too high and it will crash with a very high velocity (see the browser status line (usually at the bottom of the browser pane) for the contact velocity).

Version 1.08 fixes the "zero throttle start flame off bug." Thanks to Captain for reporting it!

Version 1.09 adds the feature to use the spacebar for button action for "hands-off-the-mouse" operation (for pilots with the right stuff).

Version 1.10 (July 7, 2008) incorporates finer granularity of the flame length.
