I am told that the BBJ will always require a LAME to sign the tech log as every sector is regarded as ETOPS. Something that is done as the aircraft may require to change destination in flight and that destination may be ETOPS.
Not exactly right - the a/c regularly do multiple leg training sorties to various ports without LAME involvement, so they can (technically) do without a LAME. However when on a VIP sector LAMEs always available.
