Scenic Landing Norwegian 787 London Gatwick Airport 

I usually use Panasonic w850 or sd600 i forget which for this but usually all full flights are panasonic. But looking at the dust marks the. I used the a7iii because i take lens off now and again

Because they call it greater London it's used as a distinction as it's an international airport because nobody knows where Crawley is around the world but London is familiar. It's the same with Stansted, Luton and Southend. I'm from Crawley and asked myself the same question.

Much like stanstead too😂

Because it has multiple rail & road connections to london

It was built to cope with extra demand which Heathrow was struggling with at the time.
