 # AirShuttle [airshuttle]
 
+A transportation mod for sightseeing tours.
+
+![TechPack](https://github.com/joe7575/airshuttle/blob/master/screenshot.png)
+
+
+## Instructions
+
+The air shuttle is remote controlled and can't be self-driven by any player.
+The means the flight route must be defined beforehand.
+
+Start/stop is always the launcher position. Chat commands allow to define waypoints.
+The player has to have 'airshuttle' privs to be able to configure the flight route.
+
+
+## Step by Step
+
+1. Place the launcher block at your preferred start position, the displayed number (ID) will be the flight number for this block.
+
+2. Specify the waypoints with `add_waypoint <id> <number> <extra-height>`  
+   You can specify the altitude relative to your current position.  
+   `<id>` is the flight ID, `<number>` are the waypoints number from 1 .. 20  
+   `<extra-height>` should be something between 3..20 nodes  
+   Marker blocks appear at all waypoints, but disappear after a few minutes.
+
+3. Deleting points again with `del_waypoint <id> <number>`
+   There may also be gaps in the numbers.
+
+4. With `del_route <id>` you can delete the route again. If you remove the launcher block, the route is gone too.
+
+5. With `show_route <id>` you can have your route displayed.
+
+5. When you right-click the launcher block, the air shuttle appears. After right-clicking the air shuttle
+   the flight starts. The only possibility to abort the flight is to leave the game.
+
+6. After arrival you have to right-click the air shuttle to get free again.
+
+
+## Further hints
+
+* The higher you fly, the faster you fly. 
+* If the distance between to waypoints is greater than 200 nodes, the air shuttle we be teleported to the next waypoint. 
+  This allows you to visit hotspots far away without spending too much time.
+* At the waypoints the plane slows down, especially with strong changes of direction.
+* There is no recipe so far, only the admin are players with creative privs can distribute launcher blocks to players.
+* Only one flight at the same time. The launcher is blocked in the meantime.
