The pilot of a helicopter that crashed in Houston last month was in contact with air traffic control moments before the accident.

The National Transportation Safety Board says a helicopter pilot was speaking with an air traffic controller when it crashed into a tower, killing all four people on board.

According to a preliminary National Transportation Safety Board (NTSB) report obtained by PEOPLE and issued almost two weeks after the incident, the pilot of the Robinson R44 helicopter, later identified as Samantha Grandbouche, was speaking to the air traffic controller and requested “the downtown loop.”
