Teacher Kathrin Goldback, who is in her 20s, allegedly told her pupils in Krefeld near Dusseldorf that she was ‘going to be a mum’ - and was looking forward to taking the next step with her fiancé.
Despite being engaged, reports suggest that Lubitz and Goldback had a very on/off relationship, and that more recently the pilot had been seeing another woman.
Goldback is now struggling to come to terms with what her partner of seven years has done, along with the stigma of carrying his child.
The couple met as teens when they both worked at Burger King in Motabaur, and stayed together while he trained to be a pilot.
They moved to Dusseldorf together four years ago and shared a home in the German city.
But according to reports Lubitz’s constant need to be ‘in control’ meant she was looking to move out of their flat and end the relationship - something which is now believed to have contributed to his heinous actions.
In the weeks leading up to the Germanwings crash, that killed 148 people on the 24th March, Lubitz was reportedly increasingly erratic, and even stopped taking his antidepressants.
This weekend a chilling transcript of the black box recording revealed pilot Patrick Sondheimer’s desperate pleas with Lubitz to open the cockpit door, after he locked him out while the former went to relieve himself.
‘Open the goddam door’ he says, before banging forcefully on it.
When a Sink Rate alarm starts going off, Sodheimer begins screaming at Lubitz, with the automated message sounding: ‘Ground. Pull up. Pull up.’
In the last moments Lubitz can be heard breathing, the passengers screaming, before everything goes dead at 10.40 as the plane hits the ground.
