This is the dramatic moment firefighters in full hazmat gear boarded a British Airways flight from London after it made an emergency landing in Italy.
Melanie Wells, 61, was on the flight which had set off from London Gatwick with her 19-year-old daughter Imogen for an eight-day luxury break in Egypt.
Shortly after boarding, Melanie says she began to feel unwell and initially blamed it on the temperature in the plane. However, she claims the situation spiralled as travellers and cabin crew also became sick.
The aircraft was forced to divert to Venice, where she says emergency services rushed to the tarmac.
According to Melanie, the plane was quickly surrounded by ambulances and fire engines as hazmat teams boarded with breathing apparatus and scanning equipment.
