remember in ROTF when jetfire used the space bridge to get to Egypt, how is this possible if sentinel created the space bridge tech?

 

I believe the pillars were different from the space bridge. The space bridge could transport TFs but wouldn't be capable of opening a gateway to another planet like the pillars did.

 

Plus, Jetfire was a seeker. That was most likely something only a seeker could do.

 

Sentinel basically reverse engineered a seeker's type of space bridge and made it at a larger scale with the pillars,

 

was it a space bridge? thought he used a transwarp drive ...

 

In the movieverse, any Transformer with a beard can space bridge.

 

this.

 

Jetfire's is personal, smaller version, and don't forget, Sentinel has direct connections with the Original Primes. You could say Sentinel stole the Tech from them.

 

Space Bridge is a Lost technology that the Original Primes and Seekers had, All seekers were on Earth, Fallen in the nemesis, The other Primes dead, thus lost technology, WHICH sentinel Prime recreated
