ahh, being able to actually get lost in echo base would be cool.  Especially since it would give the imperials a hard time trying to find the important rooms (flag points) i.e. the control room, the mdeical facility, the barracks.

Plus, weren't there multiple entrances to the Hoth cave?  I remember them talking about how Luke may have come in the South entrance in the movie, not the main entrance.

I think they have two hangars, don't know for sure

but the X-wings needed a hangar too

and I think only snowspeeders were in the first hangar together with the MF

Need to watch the movie again to see if there were also X-wings in those hangarbay, in the blueprints there was room for X-wings

it has 2 hangers. one that you saw in the movie and the other you briefly saw for about 3 seconds. which holds the transports.
