If we start with 'The Command Center executed the request and, a minute later, Cleveland Center reported that United 93 may have a bomb on board.', does it make sense to conclude with 'A minute after the Command Center executed the request the Cleveland Center reported that flight of United 93 may have a bomb on board.'
The Command Center executed the request and, a minute later, Cleveland Center reported that United 93 may have a bomb on board.###A minute after the Command Center executed the request the Cleveland Center reported that flight of United 93 may have a bomb on board.
