The Inter-dimensional Council (IDC) was initiated after the Roswell incident of 1947. The foreign capsule wreckage was taken to Area 51, in the NevadaDesert where it was studied, tested and reverse-engineered.
By reverse-engineering the advanced - seemingly futuristic technology - and using unified field theory, scientists developed a faster than light vehicle consisting of two counter-rotating cylindrical containers filled with cryogenically frozen mercury; this generates a powerful electromagnetic-gravitational field capable of providing momentum for a FTL Vehicle.
The trans-dimensional device uses a reactor-type engine salvaged from the wreckage from the Roswell event. This device allowed them to generate a distortion field around a piloted capsule which will displace it through the planes- but in this case though time and space.
The capsule is released in a low-orbit launch counter to the earth’s rotation- where it reaches faster than light speed, after which pilots will steer the capsule towards the required space and time coordinates.
