Although the American Heritage Dictionary refers to ‘entering’ or going aboard a vehicle or ship, the Israeli army’s reference to its troops ‘going aboard’ the Turkish ship carrying relief supplies does not evoke men rappelling down from a helicopter in full riot gear in the middle of the night.

A ‘boarding party’ comes alongside a ship on another ship, and requests permission to come aboard. Usually in broad daylight.
Israel could have done this, in order to inspect the cargoes being carried, which could then have been ‘safely’ delivered to Gaza.
