two trainee controllers were in on duty by themselves in the Lehigh International Airport tower
All media reports seem to suggest a 'newly' qualified and trainee controller were on duty. How newly qualified was the controller and at what stage of training was the trainee. It will probably be determined this was a legal (yet undesirable) combination.

p.s. nothing personal to either AT bod when I say undesirable!
