Word had also been received of several accidents to American pilots , and it looked as though the history of that eventful day would set a new high-water mark in the way of losses . Jack even began to fear they might be ordered to go up , which would bring about a fresh delay while communication was being established with Headquarters to verify their story . So he was really glad when Tom drew him away by suggesting that it was time they dined . At one o'clock they were at their headquarters , killing time and waiting . Jack 's nerves once more began showing signs of being frayed , or `` ragged , '' as he called it . He jumped at the least unusual sound , and alternately looked expectant and despairing . It was now close to two o'clock , and as yet there was no sign of relief .
