The "Thunder Pig" a.k.a. 727 was never a star takeoff performer with the -5 or even -7 engines.

I used about 30% fuel and it took a good bit of runway.
The 747 with the same 30% fuel did about the same, using a lot of runway. V1 would not have worked.

Oh BTW I used a lot of braking and got the Brake Temp light again!  ;D

The 757 or the A-320 series planes would do a nice job operating at KTEX.
