The rig "legs" were black plastic piping for sprinkler systems.
Kinda regret I did though - it looks rather cartoon-y. Also making the helipad so garishly obvious precludes the use of the rig for VSF aeronef gaming...
Yukikaze had wormholes that appeared over Antarctica. They lead through to an alien planet which humanity invades through the wormhole. Lots of cool dogfights. Weird incomprehensible plot.
Area 88 has a mercenary air force fighting in some un-named African/Middle Eastern country. Awesome 1970s dogfights with an annoyingly angsty, whiny, Japanese teen protagonist.
