The start procedure for a jet engine is not just pressing a button and off you go...
Step 1 - use an external compressed air source to start spinning the blades/internal compression system. (or use plane's own auxiliary power unit if available)
Step 2 - wait until a specific minimum revolution velocity has been reached.
Step 3 - then introduce fuel and wait for ignition
Step 4 - then allow the engine to become self powered
Step 5 - allow the engine to stabalize.
Step 6 - air pressure from engine one can then be channeled to engine two for its own start up procedure.

There are two 'l's in chanelled.

A lot of aircraft do including Nimrod, C-130, Jetstream, and HS-125. They are gold film window-heating elements.
Aside from cutting down glare, they also help 'soften' (or at least reduce the brittleness) of the perspex which gives you a certain amount of protection against birdstrikes.
The 'V' bombers had a gold leaf coating on the windscreens to prevent the crew being blinded from the nuclear flash.Aside from cutting down glare, they also help 'soften' (or at least reduce the brittleness) of the perspex which gives you a certain amount of protection against birdstrikes.

NASA had a test f16 that had the upper surface of the wing with thousands of slits in the outer surface. They generated a vacuum along the surface of the wing that sucked the turbulent air inside the wing surface increasing the efficiency and stall angle of the wing, this resulted in extended range and slower landing speeds.
Bloody clever these people.
