they sure did, and that wee tug went up like a goodun !!
It was on 58 attached to a 'Baby' and I was sitting beside it in a Q4 on 59 when it went. Fire boys and girls were very quick and it looked to be handled really well.
The pax got off the back while the whole aircraft was coated in foam so many of them were indeed walking past like they'd just been to a party!!!
A strange but amusing sight, to say the least!!
