This is the story of Delta airlines flight 9877. On the 30th of march 1967 a DC 8 was flying over the skies of New Orleans with a very special mission. The flight's purpose was to provide crew training. Tonight they’d be practicing the procedures for a landing with two engines out .While it may seem strange to us today. They had to take a massive 4 engined long range plane into the sky to train 3 people, you have to remember this was the 1960s, man hadn't landed on the moon yet and the simulators of the time may have been woefully inadequate in providing a realistic experience for the crew members. So their only option was to fly these training flights.
But what exactly would they be doing on this simulated two engine out approach. So here’s what the manual had to say about landing a DC8 with two engines out on one side. First you could fly the traffic pattern if you wanted. But you had to plan the traffic pattern in advance you had to avoid banking over 30 degrees with more than two engines out. At first a speed of 200 knots is recommended as rudder travel is restricted when the flaps are less than 10 degrees, flying at a higher speed gives you more control authority.
Once on the downwind leg you can extend flaps to 25 and maintain 165 knots. The minimum speed for a DC 8 on two engines is about 151 knots and 165 knots gives you a good buffer. Just a quick side note the downwind leg is the leg when you fly parallel to the landing runway in the direction opposite to the landing direction. Once you're on the base leg you can lower the landing gear and you can extend the flaps to 25 degrees.The drag from the landing gear is negligible and once on the final you can drop down to 155 knots. Maintain 155 knots and only add more flaps when you're sure that you’re not gonna undershoot the runway. After you’re ready for your landing make an approach that is no steeper than a normal approach and land on the runway as soon as possible. do not flare or float along the runway and make contact as soon as possible. That's how you land a DC8 with two engines out. If you ever find yourself in that situation you now know what to do. This is exactly what the crew were attempting that night.
On tonights flight they had a captain trainee and a flight engineer trainee and a flight engineer that was being given a proficiency check. The weather for the flight was not that bad visibility would get a bit hazy at 600 feet due to smoke and fog but other than that it was typical night. The plane departed the ramp at 12:40 am with the trainee captain in the left seat and the check captain in the right seat. They didn't have to confirm their flight plan with ATC because they had not filed one. For test flights like these a flight plan was not needed.
They contact the tower at 12:43 am, they tell the tower that they’d like to circle and land back on runway 1, The plane lifted off into the cold night and everything appeared to be normal. At 12:47 a m the pilots radioed ATC that they were on the base leg for runway 1, this means that they were flying at a 90 degree angle to runway 01. They talked to the ATC a bit more they wanted to land, come to a stop and then take off again from runway 19, presumably so that the crew that was being trained could get some hours in on the airplane.
