Hi FH1100 Pilot,
sure the pilot has some skill and they haven't done it the first time.
BUT - that doesn´t mean, that they and the helicopter are immun to failure.
Can a skilled pilot do it there - yes.
Should it be done there - well, I doubt it. I have seen things developing their own life through a little bit of downwash.
In a build up area you have no chance to know, how good a roof is build, where loose material is, you couldn't see before.
(there was a thread not long ago, where a rescue helicopter ripped open a caravan - departing a registered helipad)
And from "Oh shi...!" to a crashed helicopter it takes only around five seconds.
Just because they can do it, doesn't mean, they should do it there.
There are other areas around, less then five minutes flight - ok, half an hour drive may be (could be done into their direction anyway), where there would be much less risk.
A true professional (not only skilled) pilot would access the risks - and I doubt would accept unnecessary risks, only to save a few minutes time.
If you ask the price for safety - ask yourself, what the price of a crash is....
