[Recovered debris of the EgyptAir jet that crashed in the Mediterranean Sea are seen in this still image taken from video]By Lin Noueihed and Tim Hepher CAIRO/PARIS (Reuters) - The EgyptAir jet that disappeared last week did not show technical problems before taking off from Paris, sources within the Egyptian investigation committee said late on Tuesday. The sources said the plane did not make contact with Egyptian air traffic control, but Egyptian air traffic controllers were able to see it on radar on a border area between Egyptian and Greek airspace known as KUMBI, 260 nautical miles from Cairo. Speaking on condition of anonymity, the sources said the plane disappeared without swerving off radar screens after less than a minute of it entering Egyptian airspace.
