Smith also needed to subpoena all surviving British passengers and crew while they were still on American soil, which prevented them from returning to the UK before the American inquiry was completed on 25 May.
Smith juga perlu mengirim surat pangillan kepada seluruh penumpang dan awak Britania yang selamat selagi mereka masih ada di Amerika Serikat, sehingga mencegah mereka pulang ke Britania Raya sebelum penyelidikan Amerika Serikat selesai tanggal 25 Mei.
