With the hacked editor I made the following settings: I gave an air unit the telepad ability, a lot of hitpoints, the hidden nation flag, removed the "go to" ability and removed the rebase ability. Than I placed this unit over a land square and gave the teleport flag to other units (warrior and archers as they still did exist at the start of my mod). The teleporting units had no opportunity to teleport to other places as to the planned landing places- especially they had no chance to teleport back from these landing places as they would do so all times I did test this. Screene 1: In the next round always the following happened: A massive invasion via telepad, even if there stood units of other civs (here France) next to them. All invading units used one telepad unit until the hitpoints of that unit were consumed (much more units than the two I have read in the teleportation thread). Screene 2: I wasn´t able to destruct the telepad unit. I placed lots of fighters around the unit with the airfight mission on them, placed the fighters in cities next to the unit, on land squares next to the unit and moved on the telepad unit, I moved land units in the square with the telepad airunit on it who shared the same landtile but couldn´t do any harm on that unit (an old bug that still seems to work with C3C) and I tried to bombarde it with arty, but the arty couldn´t aim that target. Strangely enough air units could do bombing missions on the land tile with the air-telepad unit on it but didn´t get any harm by these missions. The only thing I haven´t tried yet was to throw a nuclear bomb on it. But there was one manouvre that did stop the invasion: If a foreign land unit shared the same file with the telepad air unit, the AI didn´t teleport invading units to that telepad unit. What if the airtelepad unit hoovers over a land tile that only is allowed to be passable to foot units and all units on the map but the invasion force have the "wheeled flag"? What if a special settler with a foot flag lands and creates a (resource-)city on that place that automatically gives a road on that tile ? What if this telepad air unit is optically invisible, so that it doesn´t disturb until it is used at D-Day? As C3C is very complex, I made alot of questionmarks in this post, but I thought, I inform the civ-community about this phenomenon.
