Here is the story:
I met Greg at his home and we decided to go here: 1
View attachment 1
So Greg rode is bike from his house and I followed by car with my bike and the drone.
We parked (2). My bike had an electric trouble, bad connection in the wire, so Greg took the drone case with him and we took the trail to the location.
We parked our bikes and the case in A

We started to do video in B, Greg started to jump the steps and we went a little bit on the trail after where Greg started to do slip in the turn in C, but after around 7 or 8 minutes I had to land the drone to change the battery.
Greg realized that he forgot to start his Gopro, so the time that I go back in A to change the battery, he did what he had done before.
When he had finish he came back to me, stop his Gopro and we decided to do more footage of the slip in the turn, in C.
I took-off, placed the drone in C. Greg forgot (on more time !!) to turn-on his Gopro.
And Greg fall.
So I stopped the drone, and the first words of Greg were: I hurt my head. He stayed sitting in the ground few minutes, he told me that he had like a quick black. But he was fine and joking: did you get it in the video ? I said yes and he told me with a big smile: good it will be great to see what happened exactly.
I asked him if he wanted to go back home, but he told: no let's do the shoot with the drone over the Potomac as we have planed before.
So we went back to A where was the case to take a new battery and I also took the googles who shows the view of the drone gopro and I explained him that he can wear it to have the view.
For that he had to be close of me to plug them in my remote to have power.
So I started to get down, from D to E, in the rocks to be closer of the Potomac and when I arrived in E, Greg was in D. It was maybe 10 minutes after the accident.
He told me: What should I do with the googles ?
I reply: come close to me, you need to plug them in my remote
He said: But what are we doing here ? I am confusing, what happened ?
So I came back quickly and he was totally lost.
I explained him that he fall from his bike
He told me: I was riding my bike here ? where did I fell ? Why ?
I said yes, and you were going up and down of the steps, I was flying the drone, we went on the trail, you fall
And he was very surprised of all of what I told him
I was scary but I thought that the best thing to do was to answer all his questions.
He asked me the same questions during maybe 15 minutes, looking around, trying to understand, and the last question was always" Which day are we ?"
I said "Friday"
he replied each time " Ah Friday that's good !"
And he restarted to ask me: What happened exactly ?
I was afraid that he asked me who am I, but hopefully it never arrived !
So he accepted to go back home, but I had to put back the drone in the case, and when he saw the case he told me "You came with that case ?
I told him "yes and you were holding it yourself". He was dumbfounded.
We want back to the car, he had no memory how we came, where we met, that we looked at the computer and when I asked him what he did before during the day he did not really reply.
He decided to ride back to his home and I followed him.
When we arrived home, his wife was there, I re-explained him at what time arrived the accident.
He went to the hospital and the deal was that he send me a text in the hour.
He send me one to tell me "@hospital".
I was not proud !
