Transit through Luton Airport controlled airspace (part 3 of 4)

Requested a transit through Luton Airport Class D controlled airspace from the south to north via the low level route. Luton ATC were very accommodating. 😃 After flying through Luton controlled airspace, I flew back to Denham Aerodrome via Biggleswade, St Neots, Silverstone, Princes Risborough and Amersham
