Assuming you have DirectX and Excel 97 installed on your computer . . .
1) In Excel 97, open a new blank work sheet.
2) Press F5 and type X97:L97 in the Reference box, then click OK.
3) Hit your Tab key once. (You should end up in cell M97.)
4) Press Ctrl+Shift while clicking once on the chart wizard icon (the one at the top with the blue-yellow-red bar chart).
Welcome aboard! After a few moments you should be flying. Steer with the mouse, accelerate and decelerate with the left and right mouse buttons respectively, and look for the monoliths with the programmers' credits.
You can exit the screen by pressing Ctrl+Shift+Esc. Enjoy the flight.
