During a test flight this afternoon, the 2nd test 787, ZA002 experienced smoke conditions in the main cabin as it was getting ready to land at Valley Airport in South Texas. The aircraft immediately diverted to Laredo, Texas where the crew and engineers on board evacuated the aircraft. Boeing is currently investigating the incident.
The incident does not seem to have stopped the other 787 test flight activities but that doesn't mean they won't be affected at a later date.
More on this as it develops.
