Some stories just write themselves

Like, for instance, this one:

The flight from Belgrade to London made an emergency evacuation after passengers panicked, fearing a terrorist gas attack.

But an official investigation into the incident at the Nikola Tesla Airport in the Serbian capital has revealed the fumes had escaped from a giant container of curry spices in the plane's cargo hold.

Okay, absurd enough? No, not quite:

Dozens of passengers had to flee the plane after it was returned to Belgrade and contained on a special emergency procedure runway at the airport.

Emergency workers wearing breathing apparatus helped screaming passengers off the plane before the source of the fumes was discovered.

So the curry spice (probably containing more than the normal proportion of Asafoetida) was so powerful that it caused the passengers to spontaneously scream? Or did the flight crew wind them up enough with hints of poison gas that they naturally panicked?
