Structural Failures, FOIA Releases & Key Events
Explore the sequence of events leading up to the Collins, NY mid-air explosion, the structural failures of the B-47 fleet, and the FOIA releases that helped uncover the truth decades later.
Air Force engineering teams begin documenting fatigue cracks in B-47 fuselage frames and wing roots during routine inspections.
A surge in catastrophic accidents prompts internal reviews. Several losses involve sudden mid-air breakups.
B-47E Stratojet 52-0470 disintegrates in mid-air over Collins, New York. Witnesses report a bright flash and explosive breakup.
Reinforcement sleeves (“milk bottles”) are installed in over 1,600 aircraft to address structural fatigue.
Initial FOIA filings seek access to Cold War accident reports and structural fatigue analyses.
Declassified documents confirm that the Collins crash was studied as part of the Milk Bottle investigation.
Further engineering memos and accident summaries reveal the extent of structural fatigue across the B-47 fleet.
