๐ก๐ผ๐ฟ๐๐ต๐๐ฒ๐๐ ๐ข๐ฟ๐ถ๐ฒ๐ป๐ ๐๐ถ๐ฟ๐น๐ถ๐ป๐ฒ๐ ๐๐น๐ถ๐ด๐ต๐ ๐ณ๐ฌ๐ฑ was a scheduled domestic passenger flight from Miami to Portland with intermediate stops in Chicago, Spokane and Seattle. The flight was being operated by a Boeing 720 (Reg. N724US) on ๐๐ฒ๐ฏ๐ฟ๐๐ฎ๐ฟ๐ ๐ญ๐ฎ, ๐ญ๐ต๐ฒ๐ฏ.
The plane departed Miami with an IFR clearance at 13:35 EST. A left turn was made after takeoff from runway 27L and circuitous routing was utilized, in conjunction with radar vectors from Miami Departure Control, to avoid areas of anticipated turbulence associated with thunderstorm activity. At 13:47, in response to a request for their position and altitude, the flight advised, "We're just out of seventeen five (17,500 feet) and standby on the DME one." This was the last known transmission from the flight. At 13:47:25 the altitude began increasing with a rate of climb gradually increasing to approximately 9,000 ft/min at 13:47:38.
Following this the rate of climb decreased through zero at 13:47:47 when the altitude peaked momentarily at 19,285 feet. During this climb the vertical accelerations changed rapidly from 1G to about -2G. In the next 7 seconds the negative acceleration continued to increase at a slower rate, with rapid fluctuations, to a mean value of about -2.8G, while altitude was lost at an increasing rate. Below 10,000 feet a severe in-flight breakup of the forward fuselage occurred. Both wings and vertical stabilizers failed shortly afterwards. The debris fell in unpopulated area of the Everglades National Park.

"The Board determines that the probable cause of this accident was toe unfavorable interaction of severe vertical air drafts and large longitudinal control displacements resulting in a longitudinal "upset" from which a successful recovered was not made."
