A picture of the clang can be found at hypertext transfer protocol: //www.youtube.com/watch? v=ReSm7r45_ds

  2. B52 sidelong control is by spoilers ONLY – there are no ailerons. Roll response to spoiler warp is slow, with typically a 3 2nd hold between control input and axial rotation response at normal airspeeds.
  3. The consecutive and flat stall velocity in the clang constellation ( roll down ) and weight was 110 karat IAS
  4. The aircraft commenced the bend at 180 karat IAS, with a little addition in push
  5. During the concluding portion of the bend, bank increased, with the aircraft impacting the land at 90 grades AOB, at 150 karat IAS, and with low thrust scenes on all eight engines
  6. The aircraft ab initio turned into a 10 karat headwind, which so became a tailwind in the concluding portion of the bend

    Your study should see merely the aerodynamic facets of the accident, and reason what, in your sentiment caused the aircraft to crash. You may besides do recommendations on what action ( s ) the pilot could hold taken to avoid the clang.
