Circumstances:
The airplane was chartered to perform a night local sightseeing flight over Pittsburgh with 10 passengers and one pilot on board. Shortly after takeoff, while in initial climb, all three engine stopped. The airplane stalled and crashed. A female passenger aged 17 survived with serious injuries while 10 other occupants were killed.
Probable cause:
All three engines failed after the fuel supply was cut off, and there were indications that the pilot had then allowed the Stinson to lose flying speed while attempting an off-airport forced landing, the accident occurring in darkness. It was considered possible by the US Bureau of Air Commerce that the passenger who had been sitting on two flare containers in the cockpit had precipitated the crash by inadvertently switching off the fuel selector valve with her heel.

Circumstances:
The three engine aircraft departed Springfield Airport at 2200LT on a mail flight to New Orleans, carrying one passenger and one pilot. Twenty-six minutes into the flight, while approaching a wooded area, the pilot realized he was too low and initiated a right turn to avoid the trees when the tip of the right wing impacted the ground. The aircraft went out of control and crashed some 6 km northwest of Nilwood. Both occupants were killed.
Probable cause:
It is the opinion of the Accident Board that the probable cause of this accident was an unintentional collision with the ground while flying at too law altitude at night.

Circumstances:
While flying at night in marginal weather conditions, the pilot did not realize he was too low. The airplane impacted trees and crashed in a wooded area located near Amazonia, bursting into flames. The aircraft was destroyed by impact forces and a post crash fire and both occupants were killed.
Probable cause:
The pilot committed an error in judgment in turning too close to the ground in a fog-bound area. Weather reporting facilities of the Company were inadequate to meet the conditions that confronted the pilot in this flight.
