Howling:How did The Doctor and Hila survive traveling through the Time Vortex?

It was a big plot point in Planet of the Dead that the people needed to be inside the bus to travel through the wormhole back to Earth. Then Captain Jack held on to the outside of the TARDIS while it traveled through the Time Vortex and it's only because he was immortal that he survived. In Vincent and the Doctor, paper fliers that were attached to the outside of TARDIS were burned off when it traveled through the Time Vortex.

So, in Hide, how did The Doctor and Hila jump through the Time Vortex with just a rope around them and not only use it to travel to a pocket universe but simply survive at all? Every time (that I'm aware of) that we've seen The Doctor or anyone else outside TARDIS was explained by an air corridor surrounding it...the Doctor never actually leapt into a wormhole before.
