How to unlock the Storm Warning achievement in Bridge Constructor - Definitive Guide

I've covered how to do this at 28:41 in my YouTube Video guide posted above. Enjoy! :)
On Bridge 3 of the first island, build a ramp up from the left side (by having the first piece of road at a slope of 1, the second at a slope of 2, the third at a slope of three, and the fourth at a slope of 4) and support this with various triangles of wood. Then play the level, and choose the cars. As the first one flies off the top of the ramp, you should get the achievement.
There is a multitude of ways to do this. One simple option is to create a ramp that goes up and up which will cause the vehicle to shoot into space versus cross the great divide. Another simple option is to wait until you unlock the tank truck. The tank truck is extremely volatile and let's just say a bridge crossing that fails causes things to go flying. It would be extremely rare to not unlock this trophy when that happens.
The trophy will unlock immediately while whatever vehicle is still flying through the air.
This can be difficult when using cars and trucks and it recommended you use the tanker truck as their explosions from a failed bridge crossing often propel them into the air. If this doesn't unlock naturally while working on the tanker truck maps then try creating bridges built for trucks and sending the tanker truck across as these will no doubt collapse and cause the tanker to explode.
