Actually OAH, I'm on a night shift break at the moment. Probably spoken to about 30 to 40 odd aircraft since I started work a couple of hours ago. I do know that between 3 and 4 this morning (HK) time, I will barely have time to scratch myself with freighters coming and going, only one runway in use and various taxyways closed. Maybe if I sit on my "wallet" it might make things a bit more comfortable. What will you be doing at 3.30am? Regards BB
