Can't say anything about costs of repairs but for the past 3 weeks it's being undergoing repairs on the west side of the cargo ramp, being re-skinned by Boeing and its contractor. Quite a project, was under a big white tent with 24 hour round the clock work. That has now been removed.
As of yesterday, the tail has been put back up and I believe they did a gear swing and fueled the aircraft. New GE engine back on.
Also, the work site has had visitors from senior BA officials, one of the FOs from the incident flight and perhaps others.
It is due an engine run sometime next week and if all goes well, a ferry flight out after that.
I expect the media will be in full force for that one
