Error de Java FX con NeatBeans

Hola buenas, he estado haciendo pruebas con NeatBeans y Java FX para probar su interfaz pero me da un error que ni siguiendo las pautas de un PDF desaparece, ya no se si es por culpa de mi NeatBeans o no, no lo se.

intuyo que el erro esta aqui:

Código:

Caused by: java.lang.NullPointerException
	at flightsfx.FXMLMainViewController.initialize(FXMLMainViewController.java:81)

pero no veo nada en esa fila, lo veo todo bien

Os dejo el codigo espero que me podais ayudar. Muchas gracias y un saludo!

Código:
