And they certainly flew in at Tonbridge earlier, much to the hosts' dismay.

Sunderland v Mansfield Town (15:00 GMT)
You can't tear Nigel Clough away from the East Midlands, can you?
The former Derby and Burton Albion boss left the Brewers in the summer by mutual consent to help the club reduce its wage bill during the first coronavirus lockdown.
Now, he's back, with struggling League Two side Mansfield Town, who are without a win this season.
An easy first assignment for Clough, mind - just the matter of an FA Cup trip to 1973 winners and League One giants Sunderland.

All over at Exeter, who join Harrogate and Bradford as the first three teams in the second-round hat.
No run to the third round this season for AFC Fylde.
Gillingham v Woking (15:00 GMT)
It is only two seasons since Woking reached the third round after beating Swindon Town along the way, so a trip to League One Gillingham will not hold any fear for the club from the National League.
"There will be a number of upsets and we have to make sure we are not one of them," said Gills boss Steve Evans.
While Gillingham sit 13th in English football's third tier, Woking are ninth in the fifth tier.
Woking skipper Josh Casey believes playing with no fans is a "real leveller".
