What is the ruling on someone who experienced a wet dream during transit at the airport and was late for Fajr prayer due to the unavailability of a place to perform ghusl, and is tayammum sufficient in this case for fear of the prayer time expiring?

The ruling for someone who cannot find a place to perform ghusl (ritual bath) is clarified: they should strive to perform ghusl without disrobing completely. If this is not possible and there is a fear that the prayer time will expire, then tayammum (dry ablution) should be performed, and the prayer offered. It is hoped that Allah will forgive the questioner for their ignorance of the ruling.
