The first plane hit the WTC at 08:46.
A Groundstop (for NY area) wasn't issued on 9/11 until 9:06, 20 minutes after this event and 3 minutes after the second plane hit.
Flight 93 took off at 08:42, four minutes before the first plane hit the towers. Additionally, it was known well before the groundstop order that Flight 77 had already deviated at 08:54 and turned off its transponder at 08:56.
A "better safe than sorry" groundstop may have saved lives impacted by Flight 77 (Pentagon attack), even more if Flight 93 (PA crash) had been delayed by several minutes more.
I'm sure this has something to do with the calculus.
