Friends of the Earth said it strongly supported the project and if new
transport methods were needed, the scheme "was exactly the sort of
initiative TfL should be considering".

The scheme's docking stations were not in the airport's safety zone, it
said, but a TfL transport assessment "clearly shows the cable car
passing through the passenger safety zone".

It passes over the last few square metres of the proposed enlarged zone,
not the current passenger safety zone. Planes are usually at around 2000
feet at this point, because of the steep flight paths required at LCY. I
believe the cable car will be at about 200 feet, so there's good
clearance.

I don't really know what the risks are, but airport PSZs are defined by
the CAA as areas "to control the number of people *on the ground* at
risk in the unlikely event of an aircraft accident on take-off or
landing".

In the case of a plane landing short (or overshooting) at London City,
it's more likely to plunge into the Royal Victoria Dock than hit
anything overhead. If there were to be problems at a higher level, the
high rise buildings around Canary Wharf would be the most serious
problem.
