At this stage, the reason for the emergency onboard Delta Air Lines flight DL17 London-Detroit is currently unclear.

What is clear is that the squawk code change and subsequent u-turn would indicate something significant happening onboard.

The 7700 squawk code is varied, and could account for different emergencies such as:

  • A medical emergency onboard involving a passenger or crew.
  • Something technical with the aircraft.
  • Something mechanical with the aircraft.
