The airport has got tugs to carry out the job , just as they did for the Lydd Airshow.
dont know where you got the idea about a fire truck pushing a 737,
i think that being in a forum about aviation you would know that this is not possible , unless of course this is some magic trick that manston ground ops have under their sleves.
just to add , the last 737 - 200 to visit was over a year ago
