If you ever come across those photos you`ll have a new friend for life
The floors are solid to walk on, though mass evacs have designated routes and walkways/stairs off the show scenes. However, I wouldn`t say it`s safe to jump out anywhere, on any ride. Apart from the obvious stupidity of doing so, and the risk to millions of dollars of technology and scenery, the SSE rise system is best described as being on a Matterhorn-style track. You sit in the ride vehicle, which itself sits on a chassis. This chassis is mounted on a similar-in-style-to-a-rollercoaster wheel mechanism having 4 sets of wheels, one in each corner. Each wheel set has 5 individual wheels ontop, below and at the side of the rail. Then the rails themselves are supported above the actual building floor level. This adds up to a good 4-5 ft from your feet to the structural floor. On average. The show scenes are also elevated in places, to be at the same height as the ride vehicle, but much like a train at a station there is a gap between the two - varying in distance. It dosn`t take much to think of the consequences of becoming trapped between the two. Best case severe cuts or a broken ankle. Worst case, the idiot is still there when the ride system restarts. And that`s 151 ride vehicles (or 154 depending what yor read with maintainence vehicles) moving on 1552ft of track - that can't E-Stop on a dime.
As for CCTV, it`s certainly been enhanced and made publically known in recent years, but I dare say it has always been there. Plus, these rides generally have intrusion systems (IR beams, pressure mats) but I dare say it`s off the scope of this thread to go into detail.
