He said the main focus was on making sure those involved were okay.
Mr Wickham said receiving news of the accident was a worst nightmare.
"The only thing of enormous relief was that no one was severely injured. There are plenty of helicopters in the world."
He said he didn't know yet whether the helicopter would be repaired or whether they would need a new helicopter, but said the machine was insured.
"Right now I've told everyone to catch their breaths."
Mr Wickham said the two on board were holding up "fine" given the circumstances.
"It was a bit of a shock. It takes a bit of getting back in the right space."
He hoped to see the crewman and Mr Kowalski back in the air as soon as they were ready.
A Civil Aviation Authority spokesman said they had an investigator at the scene yesterday. He said they had secured the scene and would look to move the helicopter off site.
