Probably the worst thing to do would be to use a treescape as that would connect the pilot to earth - whereas being connected simply to the power line itself is less of a hazard as helicopter power line inspectors prove on a regular basis!
Good that the pilots are safe and sound after the event. Some ejections have involved a lot of luck; perhaps one of the more amazing was that from XM604 in 1968, again through powerlines:
"The aircraft had rolled to port through at least 90 degrees but not more than 120 degrees, with a nose down angle of between 15 and 20 degrees when the Captain ejected from an approximate height of 300 feet by pulling the face blind. The blind partially covered the right side of his face because he only used his right hand to pull the face screen firing handle. Due to the attitude of the aircraft and the low height at the time of ejection the parachute had only streamed when the pilot passed through high tension cables close to the scene of the accident. The canopy caught one cable, pulled that cable onto the next one and caused an electrical short. This fused the nylon panels together which acted as a brake, and the pilot was lowered to the ground. As his feet touched he undid the quick release box and walked away."
And now back to the amateur comedians....
