There really is little wonder that the US EMS industry is being looked at deeply.
On July 4 and Agusta A109E took off from a rooftop helipad and was alerted to the fact that the chocks were still in place on the roof [they are usually stowed to one side I guess] it was then that the 'driver' recalled that he had been in the middle of a post flight tie down when the latest call came in.... as a result when he popped off to check the weather he forgot that he had left the intake bungs in place.....
No wonder the TOT was high...
Anyway they landed on checked the 109 over and decided they got away with a disaster that time!
Seems sort of unlucky he did not get as far as the pitot cover and tie-downs... might have twigged it then!
