There certainly is a lot of crap being written in here by people that don't know much about Airlines or Flying Jet A/C.
Yes the post above this is a PRIME example of utter rubbish.
1/ You do realize that the 772ER most likely wouldn't reach much above FL400 at the weight they were even with the GEAR UP!! Let alone the crew selecting gear down to Extinguish a wheel well fire.
2/ the nose gear wheel well does not have Fire detection anyway....
3/ under inflated wheels will not catch Fire......
4/ the 777 is equipped with a tire pressure monitoring system ( TPIS ) and the crew would get an EICAS message if any wheels were under inflated.
5/ I've got nothing more except utter contempt for the rubbish I read in here by people that quite obviously know nothing about Wide body Jets or the Airlines that fly them.
Please remember that the media do read this site people.
Try to keep it real.
