"Well, not exactly! There are many Elvis impersonators here, but I didn't punch any.
It also wasn't a real ejection, but "Big Shot" was pretty close to an ejection simulation! It's at the top of a 100 story tower, atop which is a 200 foot steel tower with seats attached to the outside. You are strapped in with shoulder bars, lifted slightly (for weighing, I suspect -- need to know the mass to apply the proper force, pneumatic I suspect), told to keep your head pressed against the headrest, then launched upward 160 feet at 45 mph, providing an instantaneous 4G (supposedly).
Then you stop briefly at the top before being dropped in a quick zero-G free fall. They stop you and partially raise/drop a couple of times to enhance the effect, then it's over in about 45 seconds.
The ride is on the little needle at the very top - I very nearly passed on this ride when I first saw it -- I've never felt afraid in any aircraft, but "open heights" in buildings can bother me -- I won't walk to the very edge of a roof top or cliff like many people do -- but the shoulder bars were cockpit-like enough for me -- it is really an adrenalin rush!)
Big Shot - the ejection-like ride in Las Vegas
They also have the world's highest roller coaster running around the top edge of the observation/restaurant building, but it was closed. But no worries, I later rode the Manhattan Express at New York New York -- a very fast, very steep, looping and barrel-rolling roller coaster. Another rush (4 minutes this one).
Finally I was walking Back to the hotel and passed Las Vegas Helicopters -- well, didn't QUITE pass! I took a 15 minute sightseeing ride in a stretched Jet Ranger, flying all round the garishly lit city. I arrived second for this flight, so another guest (pilot, it turns out - crop duster) got to claim the front seat! I also had no camera with me, but I enjoyed the ride more without it I suspect. The liftoff and landing (quick hover then a pedal turn to line up with the pad).
I can't resist anything that resembles flying!
Helicopter rides in Vegas
If you want to tear up the strip in Vegas wiithout breaking any laws - get USAF - the training missions are set just near Vegas and you can recognise the more distinctive buildings there. MiGMan
