I was impressed to see the Firemen and Police instinctively run towards the accident site to help.
'Onya' guys and girls. Good job.
Some of you people are being very hard on the cameraman.
In the video linked earlier he said words to the effect of -I thought the pilot was dead...I didn't know whether to go back and help him out, or didn't know if it was going to go up in flames....
Also note the difference in safety gear, with the pilot fully kitted in fire retardant clothing and Brain Bucket, the cameraman in T-Shirt, shorts and shoes.
IMO, the young fella did the right thing getting clear.
I'd be surprised if the chopper pilot had a different idea from that.
