I say no. Do not try to ride this.
I am not trying to be mean, but it is not fair to the other guests.
We were just at WDW from 9/19-9/28 and were at EPCOT for evening extra magic hours on the evening of the 26th (I think that was the date) and we were trying to get in one last Soarin' and Test Track that evening. While we were in the line waiting to get on the ride (as you line up in rows 1/2/3 and watch the pre-flight briefing) a woman and man (maybe in their 30s) were next to us (we were in row 2 they in row 3) and the woman was jokingly going on to the man about how she is terrified of heights and how she couldn't believe he talked her into this.
Well fast forward to us getting on the ride. We are all strapped in and the flight attendants are doing the check to pull on our yellow cords thing and I hear a commotion behind us. The woman is flipping out and the guy is trying to calm her down by asking the cast member how high off of the ground they will be. He says, "she (refering to the woman he was with) would only be about 4 feet off of the ground right?" And the castmemeber was like, "no, you will be maybe 30 feet off of the ground [now I am not sure that number is accurate, but it is what the castmember said none-the-less]." Well the woman went into a tizzy. She HAD to get off of the ride, with no small amount of difficulty because they had to unlock her seat and for some reason the castmembers were having a hard time doing this.
The woman keeps telling every castmemeber who walks by her that she needs to get out, and they are trying to tell her they are working on it. The rest of the riders are getting increasingly annoyed at this. Finally, after maybe 10 minutes they finally get it unlocked and she gets out of the chair, and then she stands there arguing with the guy telling him to stay, she doesn't want him to miss the ride, and they are going back and forth. The rest of us are just wishing she would leave the ride room. By the time Soarin' ends and ourselves, as well as several other we noticed doing the same, try to get over to Test Track, they closed.
Again, I am not tryng to be mean. It wasn't as though we were annoyed at having to wait for a physically challenged person to get on the ride. This was a woman who clearly knew she shouldn't have gotten on it from the beginning (when we were in line and she was moaning to the man about her terror of heights) and yet she did anyway and delayed a room full of others because of her folly.
