It's been 10 years today since the attempted suicide bombing at Glasgow Airport, which last month recorded its busiest May on record with nearly 830,000 passengers passing through its doors.
The incident in 2007 kicked off a summer of disruptions and delays as airports across the UK tightened up security in a bid to thwart potential copycat attacks.
It also set in motion a series of changes which have left the airport at Glasgow looking markedly different today.
Security bollards outside the entrance stopped the Jeep Cherokee driven by Bilal Abdullah and Kafeel Ahmed from entering the terminal, although the doors were damaged as the propane canisters within the vehicle were set ablaze.
During an interview in the immediate aftermath, security expert Norman Shanks recommended adding automated road checkpoints to prevent potential threats from approaching the airport.
A £4m investment resulted in a purpose-built security building, the Skyhub, a 4,000sq meter double-height extension with leisure facilities as well as a security search area.
To keep traffic away from the terminal itself, new carparks, drop off and pick-up zones were installed, significantly altering the flow of vehicle traffic around the building.
The number of security staff was increased by more than 50 per cent, and new x-ray machines were brought in to minimise the disruption caused by the additional security measures.
More recently, the airport's new multi-million pound pick-up and drop-off point opposite the main terminal opened in April, bringing with it a controversial £2 charge for a 10-minute stay.
Designed to ease congestion at the airport, it has further altered vehicle flows around the terminal. Within days, the changes resulted in queues on the M8 of motorists waiting to access the new traffic layout.
