The crew was involved in a local training mission at Whidbey Island NAS when a bomb attached under the right wing exploded in mid-air. The right wing detached and the aircraft crashed into the sea off the NAS. All nine crew members were killed.

The crew was completing a positioning flight from Havana to Miami for the purpose of maintenance, the propeller to be adjusted. While cruising along the Keys, a distress call was received. The airplane apparently crashed into the Strait of Florida, between Key West and Marathon. SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was ever found.

The crew was engaged in a local training flight at Walker AFB, Roswell, New Mexico. Just after liftoff, while in initial climb, the airplane rolled left and right and eventually crashed in a huge explosion on a hangar at the airbase. The airplane was totally destroyed by impact forces and a post crash fire as well as two others Boeing KC-135 Stratotanker registered 57-1449 and 57-1457. All six crew members were killed as well as two employees in the hangar.

While cruising at an altitude of 8,000 feet in foggy and icing conditions, both engines number three and four failed. The crew elected to restart the engines, without success. The airplane went out of control and plunged before crashing in a wooded area, striking the ground in a level attitude, with no forward velocity. The airplane was destroyed and all 50 occupants were killed.

While flying in foggy conditions, the twin engine aircraft struck the slope of a mountain located near Minersville. All six occupants were killed.

The aircraft registered 124893 (VP-774) departed Los Alamitos AAF at 1548LT on a training flight with nine crew members on board. In the evening, while cruising over the Pacific Ocean, the right engine failed. The pilot-in-command increased power on the left engine but unable to maintain the assigned altitude, the captain decided to ditch the aircraft that crashed into the sea off Dana Point. Five crew members were rescued while four others were killed.

Flight 2511 departed New York International (Idlewild) Airport at 2334LT on January 5 on an IFR clearance scheduled as a nonstop flight to Miami, Florida. The flight proceeded routinely in accordance with its flight plan until shortly after passing Wilmington, North Carolina. At 0231 Flight 2511 contacted the company radio station at Wilmington while over Carolina Beach at 18,000 feet, and transmitted a routine progress report. Shortly after the completion of this radio contact a dynamite explosion occurred in the passenger cabin. Following this explosion the aircraft entered a wide descending right turn and crashed 1-1/2 miles north-west of Bolivia at 0238 some 16 miles west of its intended flight path. All 29 passengers and the crew of five were killed. It is believed that Julian Frank was the author of this act of sabotage after he contracted a life-insurance for one million US$. But this assumption was not confirmed as he was himself seating in the aircraft when the explosion occurred.
No reference is made in this report concerning the placing of the dynamite aboard the aircraft or of the person or persons responsible for its detonation. The malicious destruction of an aircraft is a Federal crime. After the Board's determination that such was involved, the criminal aspects of this accident were referred to the Department of Justice through its Federal Bureau of Investigation

On landing, one of the main landing gear collapsed. The airplane slid for several yards before coming to rest on the runway. There were no injuries among the 45 occupants but the aircraft was later declared as damaged beyond economical repair.

Crash landed at Brunswick Airport. No casualties.

En route from Juneau to Annette Island, the crew reported engine problems. The seaplane later crashed in an isolated area located in the region of Ketchikan. All three occupants were killed.
