Review for LEGO set 4429 Helicopter Rescue from Brickipedia
“This set is in the line of the emergency theme which has not been around since 2006 along with 4431 Ambulance. The Hospital is two stories tall, with a red rectangular arch design on it. There is a garage for the small ambulance and a helipad on top of it for a helicopter... More which looks similar to the helicopter from the set 3222 Helicopter and Limousine but has an opening back door, that the patient can go in on the stretcher.”
