Quiet Quartet
N782SP, a 53-year-old McDonnell Douglas DC-8-72CF, climbing out from runway 05 at Toronto Pearson International Airport.
It was departing as NSP8 (Samaritan's Purse) to its home at Greensboro, North Carolina.
Serial number 46013 began its career as a DC-8-62CF, wearing OH-LFR with Finnair O/Y, on January 27, 1969.
The original DC-8-62s were powered by Pratt & Whitney JT3D-3B engines that each produced 18,000 pounds of thrust and generated 111.0 decibels of noise during take-off when not equipped with hush-kitted nacelles.
The DC-8-73s are powered by CFM International CFM56-2C1s that each produce 22,000 pounds of thrust and have a noise level of 95.2 decibels.
The newer engines produce 22% more power and generate 14% less noise during take-off.
