Air Car/Cycle max altitude

<br />I'm writing an adventure for SFMan issue 7 and need to know what the max altitude of an aircar is.<br />Currently the &quot;mooks&quot; have used an air car to on the 99th floor to....well I don't want to ruin it. <br /><img src="http://starfrontiers.us/modules/tinymce/tinymce/jscripts/tiny_mce/plugi…; alt="Innocent" title="Innocent" border="0" /><br /><br />From AD:<br /><br />[quote=Alpha Dawn -Core] When scouting, jetcopters and aircars fly at or<br />above the level of the treetops, 50 to 100 meters<br />above the ground. To stay out of sight they can fly<br />very close to the ground, following the contours of<br />the hills and valleys. This is called Nap of the Earth<br />(NOE) flying.[/quote]<br /><br />
