T2 Performance
I believe the STD from TLV to LHR was 0725.
In the summer, any delay would involve the possibility of offloading pax, due to the rapidly increasing OAT (That was after the water injection system was disabled).
I got to know the stop-end of 30 from just a few feet into the air.
I often wondered what would have happened with an engine failure at V1 + 1kt. Thankfully, no-one ever found out.
