Page 7 of the 10 page PDF attached overleaf makes it clear:
“...The Blues/Mongoose Skyhawks really were like rockets. When you jam accelerated for take off there was a noticeable push back into the seat and the post take off gear up, flaps up had to happen as fast as you read this, so as to not over speed the landing gear or flaps. If you had been cleared for an unrestricted climb you could leave the throttle at take off power; but you had to move the stick aft to the stop initially and establish a rate of climb above what the VSI could display to stay below the 250 knots below 10,000 feet limit. And you watched the air station rapidly shrink in your mirrors. If you had not been cleared for an unrestricted climb, then you retarded the throttle to 85%.
An Adversary A-4E with a mini bubble [I think this means a small 1,000 pound drop tank on centreline] could do an Immelman on take off with ease. These jets were a really good simulation of a Mig 17, but they were more maneuverable than that Mig model. Needless to say, flying these Skyhawks was always a lot of fun, but then flying any Skyhawk was always a treat for me....” Gary “Zoo” Rezeau
