flying plane script speed and positioning

**davelf** · 02-21-2012, 04:23 AM

1) Script Title: flying plane script

2) Script URL (on DD): http://dynamicdrive.com/dynamicindex4/plane.htm

3) Describe problem:
1. i have problem with the speed, how to set it at the exact speed, '100', '200', etc. Because now everything is random.
2. i want to set position at the header only like the screenshot, but know it fly all around the page.

Thank you so much
