What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Ual 799 came to an abrupt stop to avoid bta 5818 who failed to hold short of taxiway "b" as instructed. Flight crew contacted purser asking if there were any injuries in the cabin. Purser told flight crew they were fine but would be writing a report. After leveling off at cruise, flight crew was only then informed of minor injuries to 4 flight attendants. Upon arrival in mco they were checked by paramedics as all reported neck and back soreness. There is not sufficiant evidence to prove that bta 5818 understood their hold short instruction of taxiway bravo since the controller did not wait or require a readback.
