I received the following note from Bruno Verstraete:

Dear Mark,
many thanks for you mail expressing concerns about not having received an update.
we are currently full steam ahead on building the streamliner and optimizing historical things on the endurance car.
All looks good so far and the unofficial contacts with head scrutineering are going well.
This is not an official application yet, but shows our commitment to abide with all safety regulations.
we will let you know the progress as soon as anything substantial is there.
In the meantime we will send you an updated interview and some more pictures.
Kindest regards,
Bruno Verstraete
