Fourmilab Rocket is a flying vehicle for the Second Life virtual world which can be used to explore anywhere on the Grid accessible from the location in which it is rezzed. You must have land on which you are permitted to rez objects or else rez the vehicle in a public sandbox or rez zone. The rocket contains an automatic system called "RegionRX" developed by Second Life creator [Animats][https://marketplace.secondlife.com/stores/207994] which recovers from many (but not all) of the calamities which can befall vehicles when crossing from one Second Life region to another.
The rocket includes an autopilot which will automatically steer the target to a destination specified by name or SLUrl, adjusting its cruise altitude to avoid terrain and, on arrival, automatically landing at the designated altitude. The pilot can take over from the autopilot at any time to avoid obstacles or just look around, with the autopilot resuming its course after ten seconds.
The rocket can monitor a number of SAM sites, specified by their grid co-ordinates (name or SLUrl) and, when the autopilot is engaged, automatically plot a course to evade threats (ban lines, prohibited parcels, etc.) with the least diversion from a direct course to the destination.
Commands, submitted in local chat, permit configuring and operating the rocket. These commands may be supplied automatically from scripts stored in notecards to, for example, perform complex missions with multiple waypoints.
The rocket may be used a bomber for games. Anvils may be dropped from the rocket by touching its body, entering a chat command, or tapping the FORWARD and BACK control keys simultaneously. Anvils drop and leave a temporary impact marker where they hit. Anvils and impact markers automatically disappear so they don't create clutter. (You must have permission to rez objects in the land above which you drop an anvil.)
This repository contains all of the software and resources, including programs in Linden Scripting Language, textures, notecards, and development documentation, tools, and resources used the model and its development. The actual model is built within Second Life and these components are installed within it.
The complete model is available for free in the Second Life Marketplace. This repository contains everything in the model (except the prims, which are objects built within Second Life), plus additional resources for developers who may wish to extend or adapt the model as they wish. The model is delivered with "full permissions": those who obtain it are free to copy, modify, and transfer it to other users within Second Life.
