SNA take off's are safe. All planes that fly into and out of SNA are operating well within their restrictions for that airport and situations.
When a plane takes off out of SNA, due to the short runway, the first thing that is done is the break is held on while the engines throttle up. There is a spool time on the engine, as the power is not instantanious...it takes time to get the engine to 100% power. At most airports with long runways there is enough room so that the pilots dont have to hold the breaks, inorder to skip that spool time.
Next, the aircraft will rotate at no more than 5 degrees just like at anyother airport. As it builds speed, the aircraft can begin climbing at a steeper angle. The aircraft (esp. the 757) can climb very very steep, but there is a passenger comfort issue, so what you see at SNA is on the steeper end of that pax comfort thing.
When the plane has to throttle back as it aproaches Newport Beach, the pilots push the nose down to level the plane out. This avoids the aircraft from stalling. If that is done properly, there is no danger with the SNA take off.
In addition, all commercial planes are built to handle short field take off's as well as operating in all sorts of conditions. Operating in SNA is not the same as operating in LAX, DEN, SFO, DFW and so on. There are more airport restrictions in SNA, but the plane is built for it. Trust me, flying out of SNA can be done well within the planes operating standards. If a plane can not operate out of there, then it wont fly in there.
