The aircraft involved, one of the carrier’s 43-strong fleet of Boeing 777-200ERs registered G-VIIP remained on the ground in St. John’s for about 36 hours before continuing to Gatwick on March 16, 2024, taking four hours and 18 minutes to return to its base airport. The aircraft has since completed rotations from Gatwick to Tampa (TPA), Bridgetown (BGI), and Orlando (MCO.
Its base airport is Gatwick. I'm sure you know where that is.
No, there are no "holes in the official story". The aircraft being a Boeing product has nothing to do with the pilot falling ill.
I'm not going to flame you for your comments (this time), but I will note that you deserve a thorough flaming for them.
The plane stayed on the ground for 36 hours. The passengers “were rescued by another of the airline’s Boeing 777s”.
