Theory with some possible insight.
- Aircraft cleared for TO on VHF freq
Tug spoke to tower on Walkie Talkie (seperate freq).
Crew couldnt know/see ATR due RWY hump/slope from threshold?
By the time it hit, 60-70kts , too late? Abort. Lucky no casualties.
Tug tried to "speed up" when saw AC coming but not fast enough?
Evening news, hello.
