Deep cleaned using military grade decontamination equipment......
Had flash backs to brooms, buckets, hand pumped plastic garden sprays with detergent in it, plastic noddy suits over NBC kit, plastic sheeting, bodge tape, drip trays and fullers earth...... One hopes they have improved since then, but I doubt it.
i still think that the fact the drivers were not protected was lax, they mutter on about pax were 5 rows back etc, but they still need to walk past his seat.
