More info from Shanghai!
The same poster as above (vernmei) also posted a video to Sina, a Chinese microblogging site, which you can find here:http://video.sina.com.cn/v/b/78096945-1739249195.html
The video contains lots and lots of footage of teams who have just received their clue at Longyang Road Station, but seemed to take forever to stream for me, so here's a summary of the video with some stills:
First down the stairs are the long-haired guys, followed closely by the blonde girls. They both spot the cabs and go running.
A little further back are Natalie & Nadine, while right behind them are the M/F team (muscular guy with headband) and Jaymes & James.
Also with them are the green mohawk guy and his partner, who thought it would be a great idea to run the wrong way down the upwards moving escalator!! I sure hope that footage makes it to the show.. The female takes quite a bit longer to make it, and it sounds like Mr Greenbeard shouts 'Come on Kelly, run!'
Next we cut to footage of four of the teams frantically trying to find a cab (with the exception of the two all-female teams). As the M/F team with the green bandana runs towards the camera, I'm fairly sure the girl says 'James!' (which would be really confusing because then we'd have 3 racers called James/Jaymes). More likely she's just calling to one of the Chippendales guys.
That pretty much settles which teams were on the first flight.
The footage then cuts again, and we see the speculated father/daughter (?) team queuing up in the same location for a taxi. Coming down the escalator at the same time are Trey & Lexy. They join the queue and both teams start asking locals if they can jump the queue.
Next we're looking at Trey & Lexy getting into a cab. They are being filmed, so Trey shuts the door for effect, then reopens it for the sound guy to jump in!
Now we cut to the Michigan guys hunting for a cab.
They quickly get in and zoom away. On the opposite side of the road we see Brent & Josh appear. They realise they're on the wrong side for cabs and cross back over. Brent asks 'Which way's the sports centre? Is it this way?'. Josh then asks someone behind the camera 'Do you speak English?'. Brent asks 'Will the taxi driver know how to get there? How far is it?'. The girl tells him it's about 30 minutes. The boys jump into a taxi but the sound guy asks the girl's name, and asks her to sign a piece of paper.
The only team seemingly not accounted for in this video are Amy & Daniel!
