fire services were called out to brand new JAL B787 JA829J (delivered dec 21, 3012 I mean 2012, of course ) at Boston-Logan due to smoke coming out of the cargo bay/electronics bay when the plane was at the gate at BOS this afternoon (well, 1700 CET, that is... don't know the time in BOS but definitely earlier in the day ). No injuries, cause or extent of damages reported yet AFAIK.
