In the proud tradition of "Absurd news from Belgium": the terrorists took the taxi to the airport. The taxi driver recognized them from security footage and this helped the police to quickly find the place they made the bombs - apparently no-one thought it was a bad idea to take the taxi right in front of their Den of Evil, still fool of bomb-making materials and their buddies. That's not the absurd part. They'd ordered a large taxi, but when it showed up, it was a smaller one. They couldn't fit their 5 explosive suitcases in the trunk, so they only took three and left the other two behind. They could've taken a second cab, they could've waited for a bit, they could've rented a car in the first place, they could've put the suitcases on their laps, but no - their solution? Just leave 40% of their payload behind.
Belgian terrorists, ladies and gentlemen. Not the sharpest tools in the shed.
