"This flight was on primary radar when lost. Hence this is nothing like MH 370."

so what else than midair breakup could happen to get lost from the primary radar? (provided it was not on the limit of radar coverage area)
Low height. Electromagnetic waves as used to by radar follow quasi-optical rules, so limits imposed by the earths curvature ("below the horizon") apply here as well.
