The obvious is landing too long on a fairly short runway with not enought stopping distance very very easy for a first solo student to do with no experience.
I have even seen a new PPL do that domolishing a hedge at the end of the runway when if he had touched and gone there would have not been a problem.
To say that a first solo should have judged it all and gone around is asking a bit much?
The other probably less likely is a runway obstruction!
touch-and-go will almost certainly require a longer distance than a full stop
Totally untrue!!! Unless you have almost stopped when you decide to go I have touched and gone in a private jet and twin with no more than 200 metres ground roll for real reasons.
You dont give him the proper tools to deal with that situation? Crazy!
