Continuing with the "Airborne" project. Here's an RF-4C Phantom II refueling behind a KC-10 "Tanker". The Yellow/Red/Greenish line down the center of the canopies is the reflection of the In-Flight Fuel Probe. Additionally, the Pilot watches lights under the KC-10 guiding him to maintain a certain position while refueling. The KC-10 can transfer 10,000 pounds of fuel in approximately seven minutes. Try that at your Gas Station!!!
