Very close indeed. I had captured that while flying but looking at the ready video in the IMAC later on I was pretty close.
It was very fun to make this one. The range was not the concern as I had full signal video and radio all the way (except for the moment I approached for a possible landing).
Yes, in fact I lost video signal at about two meters above him. I could have selected automatic landing though but thought that was too much risk already. I was in fact in the shade a high building I had overflown seconds before.
