some good points gents,the circumstances at the time had one of the crew standing out with the area and the transfer completed with the ambulance pulled away. in the event i didnt go for a nose as i assumed the crew were about to start up again and the outside crew was on startup watch.
Speaking for myself i have had a fair bit of contact both up (hence the wanab) and on the ground and would just fancy a look.
Rotors turning in my humble opinion would be a no-no.
