The series gave the impression it was straight into 300ft with no stepping down.
Certainly seemed a bit sporty and did show the instructors being nervous - admittedly this was on the OCU.
I do find it surprising that the USAF in the UK seems to have found low level in the last few years. What's more, If I remember correctly they used to be pretty much limited to 500ft, now 250ft seems to be the norm.
I assume when F-35 comes on stream LL will be needed less. And perhaps with the exception of the RAF will be deemed a luxury that is too expensive to train for at all.
