I ran a campaign with a Empress Mavara class ship and the first session had them misjumping (a fault in the drive) and crashing on a TL3 world - in a lake. They had literally a few mioutes of real time to grab gear and get out before the ship sunk. The next four years of game time was their world spanning adventure to get their ship
1) Out of the lake
2) Flying again.
The planet was a lost Solomani colony. The political situation was akin to the US war of independence. The players had to survive harsh winters (think Valley Forge), help fight battles, travel by ship to the main continent and loot bits from the Original Ship that brought the colonists to the planet and get back. Just getting their ship refloated was a mission. They had to co-opt the locals into helping them, make temporary patches to seal their ship, build pumps, refloat the ship and drag it to land. That took six months to achieve.
The population was descended from humans of African ancestory who left Earth to establish their particular Utopia somewhere. It was probably the most fun I have had refereeing Traveller in my life. One of the players even converted to the local religion - the Universal Church of Voodoo.
Probably the funniest moment was in the battle to help their new allies take a fort and town to winter in, the character who had salvaged his combat armour was knocked off his feet by a volley of musket shots, and tried to throw a grenade at the ten guys who were rushing up to hold him down and find a place to push a bayonet through. He fluffed his roll and the grenade went off next to him. He got a badly wounded leg. Their groups medic could hav epatched him up with no problems, but he was dragged to the Regimental Surgeon who, despite his protestations, sawed his leg off in true low tech fashion. The engineer made him a peg leg out of wood fitted to his combat armour.
