As a teenager and with the suitcases out of the loft we heard the news that Courtline had gone bust at the height of the summer season. We were supposed to be off to Spain in a couple of days with Pontinental Holidays from Luton, which was the foreign arm of Pontins Holidays. The holiday was saved as our Courtline 1-11 was substituted for a Dan-Air Comet. Not sure why Dan-Air would have a spare aircraft in the peak summer period but it saved our holiday.
I can remember even then that the aircraft interior looked very dated compared to a 1-11 and shook like there was no tomorrow when the aircraft reversed engines on landing back at Luton.
